Frog(toad perhaps?) I.D

[Froggette]

Hello Everyone,

I found a frog/toad in my filter, and am curious as to the species.
I have kept Leopard frogs and Green frogs, both lovely. I also have an african dwarf frog in my aquarium, Jemima.
He is no longer in a jar, no worries. :P and I'm not planning on adopting him...even though I would love to!
