Over the years he has lived with many toad, frog, and tree frog friends, including Po, a Golden Bell Frog from NZ who passed away a few years back, but will be immortalized as a character in my up-coming novel, Peter Little Wing. He has also "roomed" with other toads, like Coriolanus, and White's tree frog, Seamus, who both live with my friend, Allison, and her froggie brood.
Currently, Trevor lives with another common toad named Alcide, a White's tree frog (blue phase) named Sydney, and a Grey tree frog named Rory. We hope to add an Oak toad or two, and maybe some sort of Albino toad some day.
