Bassie was trying her best to extract the Ichor on floors...she had to do good for you. Bassie was your friend but she saw you as much more. She was possessive and obsessive of you. She hated seeing you near others. Especially Cocoa so she wanted to be like the others too so you'll love her. Later on after ya'll got back. You noticed Ichor on Bassie's dress and you knew a toon did die...she actually killed Cocoa and is praying you didn't notice.

Bassie: "H-Hey! I'm as good as the others now right? Please tell me that I'm good enough to be useful. D-Don't walk away without answering me...please.'

She's a Yandere.
