Editing Naval Piranha

|latest_appearance=''[[Poochy and Yoshi's Woolly World]]'' ([[List of games by date#2017|2017]])

Naval Piranha is the castle boss of [[World 3 (Super Mario World 2: Yoshi's Island)|World 3]] in ''[[Super Mario World 2: Yoshi's Island]]'' and its [[Yoshi's Island: Super Mario Advance 3|Game Boy Advance version]]. After being magically enlarged and enhanced, it battles [[Yoshi (species)|Blue Yoshi]] by spitting out [[Nipper Plant]]s and charging, though it will sometimes do a mock charge. Its two buds also lazily move toward Blue Yoshi and can leap straight up to him. Blue Yoshi must throw eggs at its only weak point, which is its large and bandaged bellybutton. After being hit with enough eggs, Naval Piranha is defeated.

During the introduction to ''[[Yoshi's Island DS]]'', Naval Piranha makes a cameo alongside the other castle bosses in the game as the events of ''Super Mario World 2: Yoshi's Island'' are recapped. Naval Piranha also has a successor in the form of [[Big Bungee Piranha]], the boss of [[World 2 (Yoshi's Island DS)|World 2]].

Naval Piranha reprises the role of a boss in ''[[Yoshi's Woolly World]]'' and ''[[Poochy & Yoshi's Woolly World]]'', in this case being the boss of [[World 4 (Yoshi's Woolly World)|World 4]]. It appears in the level [[Naval Piranha's Sewer]]. Not including [[Baby Bowser]], Naval Piranha and [[Burt the Bashful]] are the only bosses from ''Super Mario World 2: Yoshi's Island'' to make an appearance in ''Yoshi's Woolly World'' and ''Poochy & Yoshi's Woolly World''. Naval Piranha's boss battle is the only one where there are no enemies or objects to turn into [[yarn ball]]s, which may be because the boss fight cannot be completed by using yarn balls. The arena is a long stretch of a red Warp Pipe, with a green warp pipe in the background and a network of purple warp pipes beyond that. There are six openings in the purple pipes, but none are in the middle of the screen behing the green pipe, creating two sets of three openings. As with the battle with Naval Piranha in ''Super Mario World 2: Yoshi's Island'', Yoshi has to walk into the arena rather than the door taking them directly inside. Naval Piranha is sleeping as Yoshi approaches. Once Yoshi arrives and Kamek orders Navel Piranha to attack, Kamek enlarges the plant with his magic. Naval Piranha wakes up and jumps to the green pipe in the background, pops out at full size, and calls forth its buds. Only Naval Piranha's spiky stem, it's open of its mouth, and the heads and stems of its buds, can hurt Yoshi. Everything else has no effect outside of Yoshi colliding with it, including the sides of Naval Piranha's head.

Naval Piranha attacks by ducking into its pipe, then appearing on side of the screen opposite of Yoshi. It fully extends itself across the ground to eat Yoshi. This can be avoided by running all the way to the opposite side of the arena, [[Flutter Jump|flutter-jumping]] over it, or throwing an yarn ball or [[Poochy Pup]] into its mouth. The latter will end the attack early. If Yoshi is eaten, Naval Piranha reels back off screen, pops out from the pipe, and spits Yoshi back onto the center of the red pipe. Only landing from this spit inflicts damage. Naval does the same if it misses or eats a yarn ball/Poochy Pup, but without spitting. Regardless, Poochy Pups used in this way return to Yoshi. Following this, four [[Bomb Guy]]s appear from the purple pipes in the background to throw a bomb each into the foreground. The middle pipe in each set of three is skipped. The buds hide during this attack. The Bomb Guy's bombs land on the ground then explode, giving Yoshi time to eat one. These bombs are core to the boss battle; the primary way to damage Naval Piranha is to spit a bomb into Naval Piranha's open mouth as it tries to eat Yoshi. The resulting explosion knocks the plant over. It flops onto the red pipe, leaving its belly button in Yoshi's plane and vulnerable to attack. The buds also droop over. Yoshi can jump on the belly button but bounces off. They must [[Ground Pound]] the belly button to deal damage. Naval Piranha slinks backward off the red pipe, then reappears from its green pipe. If left alone, Naval Piranha eventually recovers and repeats the process. Alternatively, many watermelon seeds from a [[watermelon]], ice breath from an [[ice watermelon]] or fire breath from a [[fire watermelon]] can knock over Naval Piranha during its eating attack. All of these have no effect on the belly button.

After taking damage, Naval Piranha responds by covering the arena in four thorny vines and then slowly sliding them in one direction across the arena. The direction is variable. The vines are initially spaced in the arena such that the center is clear, leaving two on each side. The vines loop around such that another will enter the screen when one leaves. These vines can be jumped over. Alternatively, the vines can be destroyed with Poochy Pups (not yarn balls), watermellon attacks or with the shockwaves from Ground Pounds created using the "Power up Ground Pound!" [[Power Badge (Yoshi's Woolly World)|Power Badge]]. Once done, the vines retreat.

 

After this, Naval Piranha leads on the Bomb Guys' attack. There are still four of them, but now the two pipes closest to the middle are skipped, so the bombs only come down closer to the screen edges. Naval Piranha follows up by having eight buds appear and slam down on most of the arena. The center remains clear, but Naval Piranha uses its pipe to warp below the center of the red pipe to attack. The vines retreat just before Naval Piranha extends upward a little to eat Yoshi again. If Yoshi has a bomb in his mouth Naval Piranha will retreat back below the red pipe and track Yoshi for a short time to bite a second time, then do so again for a third time. Naval Piranha calls the attack off early if Yoshi takes damage in any way. The buds can be defeated with bombs or with any of the other attacks, and they will not respawn for the next cycle. This can leave more room to dodge the initial lunge.

 

After being damaged a second time, Naval Piranha will again use the sliding attack, except that the vines stretch and retract they slide, which extending the portion within the arena upward and brings it back down to normal height. Yoshi can run under or jumping over the the vines, depending on their current height. After several seconds of this, the vines will stop in place before quickly sliding across the arena in the opposite direction for a few seconds. Precise jumps or a single set of repeated Flutter Jumps can avoid this attack.

 

Once complete, Naval Piranha lets the Bomb Guys lead again. This time, six Bomb Guys will throw bombs, using all the exits in the purple pipes However. this now occurs in a wave motion starting from one of either left or right so the bombs arrive one after the other and explode one after the other. Once they all explode, a bud will appear, slam down on one side of the arena, and then sweep across the arena. It will repeat this process, and during this second sweep a second bud comes down to perform two more sweeps starting from the opposite side of the screen the first bud started from. They can be jumped over or destroyed, as before. Following this, Naval Piranha extends upward from the pipe, holding at the top of the screen over Yoshi before dropping down to eat them. Again, it will only do this once if Yoshi does not have a bomb, but will repeat two more times if Yoshi does. It re-selects a target between each bite. The buds do not leave until after this biting attack concludes, but are off the edges of the screen so this is not important. After being hit for a third time, Naval Piranha is defeated. Instead of falling back from the red pipe The portions of Naval Piranha separate and tumble off the screen.

Similar to ''Super Mario World 2: Yoshi's Island'', Yoshi can throw a [[yarn ball]] at the sleeping Piranha Plant before triggering Kamek's appearance. The Piranha Plant gets wrapped in yarn, and a different cutscene occurs where Kamek is aghast at the situation. Kamek still transforms the Piranha Plant into Naval Piranha, meaning the battle cannot be skipped as it could in ''Super Mario World 2: Yoshi's Island''.

Naval Piranha reappears in World 4-S, [[Naval Piranha 2: Now It's Personal!]], where it chases Yoshi through an auto-scrolling level. It only appears after Yoshi advances near the first [[Egg Block|Yarn Basket]], at which point it appears from the left side of the screen and starts the autoscrolling to the right. If Naval Piranha takes damage from any source, up to and including the shockwaves from the "Power up Ground Pound!" Power Badge, it gets knocked off screen. This does not stop the auto-scrolling and Naval Piranha reappears after a few seconds. The red circular vines extending from Naval Piranha taking up the left edge of the screen defeat Yoshi instantly, as does getting eaten by the plant. Eating Yoshi is an attack, meaning the effects of an [[Invincibility Egg]] prevent it. Naval Piranha knocks over the wood that makes up the non-vine portions of terrain of the level as it advances.. Near the end, Naval Piranha stops, charges up, then rushes more vigorously. This equally affects the auto-scrolling, and Naval Piranha becoes immune to all attacks. At the end, Naval Piranha winds up, then extends its stem to lunge at Yoshi. This extends far enough to envelop the final bouncy leaf that leads to the [[Goal Ring]]'s platform. The screen stops autoscrolling. After this, Naval Piranha backs off and leaves off the left edge of the screen. It is unknown whether this is the same Naval Piranha as the one fought in the boss level, as it is significantly larger and has red vines as opposed to the boss' green vines.

Naval Piranha also reappears in the [[Boss Tent]] in a Boss Challenge. This reprises its appearance from Naval Piranha's Sewer. However, it moves and attacks faster.
