Does anyone know what type of frog this is?

This beautifully marked frog visits our garage regularly. We had to move him/her out recently to a pond area but sure enough a week later it was back in the garage.

Reminds me of Jackie French’s wonderfully illustrated children’s book Hairy Charlie and the Frog, one of my favourite children’s books. No matter what Hairy Charlie tries the frog comes back to his letterbox. Wonderful illustrations by Stephen Michael King
