Dreamcap Captain

Dreamcap Captains are purple, supposedly layered Capnap-like creatures that appear in Mario & Luigi: Dream Team.. They appear in groups with Dreamcaps and they are the captains of the groups that makes sure they are able to attack each turn. 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.

Dreamcap Captains and Dreamcaps battle in clusters, and thus attack as a group. 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 these called Dreamcap Captain Rs appear later on in the game.
