I thought this crossover was due to Cutie Panther, but then
Jaguar (kemono friends) wiki said: ... She was given the catchphrase "Wakaran" ("I don't know" or "I don't get it" depending of the context) by the fans after saying the phrase in episode 2. Since then, fans have been putting her in as much out-of-context situations for her, eliciting this response and it's alternate version: "Zenzen wakaran" ("I don't understand at all")
Where Maki often says 意味わかんない - "imi wakannai" - "I don't understand"...
