Multicorns mental issues(definitely not related to my mental state currently)

Multicorn, along with Conbi rightside and CNLER-F (Expunged) are suicidal, but multicorn is way different. He likes to visit the trix cave, grab loose dripstone, and try to stab himself with it. But since he is 4 demensional, all efforts have been in vain. He is highly protected by Gambi and CNLER-F. (Because he is formulated by a bunch of iron particles, when he was created, godibi made him like a computer, that's why he is highly vulnerable.)
