Mr/Mrs Squirrel is a little bit like McSquizzy from Open Season mixed with Skipper from Madagascar. I would love to build in a Mr Squirrel Jr of some description into this story and have some fun with it if the comedy is right. He knows everybody and guards his tree with his life. It is where his nuts are stored for the winter. In the sense of the story as it sits, He is a bit of a 2 sided character, He has his harsher and softer side and is also comforting and reassuring Rex when he meets him in the park. But I'd like to Flesh him out a little more with the right Voice Actor making him more of a comedy character with his own arc.
