Lob-omb
Lob-ombs are yellow cube-shaped robots that appear in Mario & Luigi: Dream Team. Lob-ombs have green eyes and wheels for feet, and uncommon for Dream World enemies, they do not appear on the field, making Mario and Dreamy Luigi have to enter a battle with a Skipdrill or Dreamy Sandoon in order for them to fight one. The name Lob-omb comes their bomb lobbing trait.
In battle, a Lob-omb may attack by moving in front of Mario a fair distance away, and lobbing a bomb at him. Mario must face the bomb and hammer it away in order to avoid taking damage, in the case of the bomb getting knocked forward, it will usually explode near some enemies, damaging them in the process. If the Lob-omb jumps then lobs, the bomb will end up behind Mario. If the Lob-omb lobs the bomb with its right arm, the bomb will end up by Mario's right, in the foreground. If the Lob-omb lobs the bomb with its left arm, the bomb will end up by Mario's left, in the background. If the Lob-omb lobs the bomb with both arms, the bomb will end up in front of Mario.
A Lob-omb may also take out three bombs, the real bomb having an explosion mark on it and getting itself turned around in an attempt to prevent the player from knowing which one was real. The Lob-omb will juggle them either clockwise or counter-clockwise before throwing them one after the other at Mario. The real bomb's identity will later be hinted as that would be the one that flies straight towards Mario. Mario must hammer the real bomb as it's about to hit him to knock it back at the Lob-omb and avoid taking damage.
A stronger version of Lob-ombs called Lob-omb Rs appear later on in the game.
