To knock them out, you need to open the eggs that are in the Geode worlds, starting from the second shooting gallery, respectively, and in 5 they are also there. The more uber, the greater the chance of finding them.
They are located in dead ends, you need to run to its end to find it. It is worth understanding that not every dead end has them, even if it is 5 shooting galleries.
