Dreamcap
Dreamcaps are red, supposedly layered Capnap-like creatures that appear in Mario & Luigi: Dream Team. They appear in groups with Dreamcap Captains and they are the followers of the groups that attack with the Dreamcap Captains at their decision. If the player defeats all the Dreamcap Captains in the Dreamcap group, the Dreamcaps will huddle together and one will run away with each turn. If all Dreamcaps are defeated and the Dreamcap Captain(s) is/are left standing, it/they'll summon 4-5 more Dreamcaps to then be able to attack.
In battle, Dreamcaps and Dreamcap Captains battle together in hordes. They may attack from the background, charging towards Mario in rows, all of which Mario must jump over to avoid the attack, or with precise timing, can land on the Dreamcap (Captain) that's lined up with him. The group may also just charge towards Mario as a whole, which Mario must jump on or over to avoid the attack, or if there's a safe opening in the Dreamcap formation, Mario can also step in line with the opening to avoid the attack.
A stronger version of Dreamcaps called Dreamcap Rs appear later on in the game. Additionally, Dreamcaps sustain critical damage from the Luiginary Flame Luiginary Attack.
