So I always love the idea of Umbri taking care of children, since she has yet to have any of her own yet. And I always love seeing her taking care of a certain skunk sweetie. My guess would be that Sabrina has to leave someone to take care of her younger sister due to work shifts and Zig won't be able to help this time, so Umbri volunteers (yes, as in no payment) to handle it.

This was a great piece done by  maxblackrabbit at this years FWA. Hope you like it as much I do!
