Clambering Crawbster

The Clambering Crawbster is definitely a unique boss encountered in the game Pikmin:The After Years. It has red skin like its counterpart, the Segmented Crawbster, but it has a brown shell as opposed to a blue one like its relative. It is encountered in Pikmin 4 (Wii U) as a mini boss.

Attacks
It, like the Clambering Wraith, now has he ability to climb up walls and the ceiling because of the spikes that are now on its shell. It cannot be defeated the same way as you would for a Segmented Crawbster because it will end up climbing the wall. It still has the rolling attack of the segmented Crawbster though. If it manages to get on the wall, it will head towards the ceiling. Once on the ceiling, it can do one of two attacks. It can either smash the ceiling causing boulders to fall or it can fall off the ceiling. If it falls off the ceiling, it will create a large shock-wave that may malfunction your captain's suit. Hide in an alcove to avoid the attack. Unfortunately, for the Crawbster, its spikes will get stuck in the ground and it will now be susceptible to attack. It has less health than the Segmented Crawbster, but this beast makes up for it in strength and annoyance.

How to Kill
To kill this beast, lure it next to a wall so it can climb up. When it reaches the ceiling, wait for it to fall down and land on its back. When it lands, it should be unable to move, making this a perfect chance to attack with Purple Pikmin. However, it will cause boulders to fall, so avoid them and this boss should be gone in about 2 turns.

In Pikmin 4
It reappears, although it has lost its ability to make boulders fall from the ceiling.
