Silver trophy28.1% of playersRareBase game

Feather Cluster, the fifth galaxy, holds 48 Bots. 41 are in its seven levels. The boss level, Falcon McFly, opens once you have finished the first five. The other seven are in side levels that appear when you fly into something on the galaxy's map:

Birdy Barrage, Shocking Behavior, Slowdown Showdown and To The Beat!: in the upper left, hit an asteroid, then fly in circles through the stars until a second asteroid appears in their middle. Hit it to open the Lost Cross Void, a short level. Finishing it opens all four.
Djinny's Revenge: a big asteroid in the upper right.
Retro Rampage 5: a UFO carrying an asteroid at the top.
Crumble Rumble 5: a fast asteroid right above the boss level.

The checklist has every Bot, and PowerPyx's level guides have a screenshot of each.
