Like I strongly believe that blob rabbit bitch is at lest part remint they glow purple in parts of there skin and honestly i head canon that he makes glitchtrap more aggressive if anything mainly from the remint he survives off he needs that remint to stay alive as his corpse has evolved to be dependent on the blob rabbit for the goo to heal wounds

Whats the other parts ???

I don't know but i do understand that I think they recat negatively to stuff like this:

•any form of water
•salt oddly enough
•brightness

They are a immortal demonic creature that feasts on fear and trust it wants there vessels to be dependent on them so they watch as long as its needed then they approach it takes longer if there chosen vessel has siblings or people who care about there those victims are difficult to manipulate and entertain

So far glitchtrap is the longest living vessel they haven't destroyed or trown away because he is fun to mess with and won't willingly try to leave they know this well.
