In Pikmin 4 (Wii U)
The Ultimate Crawmad is the fifth major boss of Pikmin 4 (Wii U), found at the Sandy Beach. It is a giant yellow crawmad that has red eyes, and purple dots on its exoskeleton. It somewhat resembles the Bug-Eyed Crawmad in both shape and size. Juvenile Ultimate Crawmads appear in Sandy Beach also and are fought as minibosses. The Ultimate Crawmad and its offspring stand out from other crawmads in that they spew poison from their mouth when agitated, in addition to the regular attacks they use to subdue their prey. Much like with the Bug-Eyed Crawmad, only its eyes are vulnerable, and when they both are significantly damaged the boss will flip over and expose its tender belly.
