When a frog lives in the pipe behind your house, odds are it should be green right?

This frog has hung around the house living in a pipe for a few years now and well its an albino frog, it sometimes comes out, but now its probably hibernating, I like it in the summer time as it makes a somewhat whiny croaking sound and annoys my dad a little bit as it croaks at the oddest of times, like dinner time, when we have guests over etc..
