>>109901780She took a like...5 month? long hiatus and rebranded away from a mouse-based persona because she didn't feel like it represented her anymore and wants to redesign her mascot/fan personification (the Sleepyhead) along with it at some point (but also said he may just come back if they can't come up with anything organically). She said she doesn't actually like mice that much (they're okay, just not her favorite and she actually likes rats more) and she wanted to have a better way to express herself creatively on stream The sleepyhead is just a funny little mouse guy that people liked and generally had a high level of presence in thread culture/OC creation but they dramatize everything as cuckoldry (plus the guy who drew those just said he has an ntr fetish)
It's really not that deep.
