Chii has an extensive background in babysitting by this point. I don't think she'll mind dogsitting that much.

I'm guessing that animal buzzlume will be akin to "individuality" or something. That way, you'll have Vivi figure out an identity beyond merely copying Chii and it fits with Chii's cryptic muttering about needing her own style at the end of last episode. Plus, it fits neatly with Mii's continued arc about moving in a separate direction from Himari.
