Please help, I've had my African Dwarf Frog, Miss Piggy, for 1.5 years. She (found out hes really a boy) has recently gotten a discolored lump near her stomach. I don't know if I overfed her or why the lump is there. She is acting completely normal, has an appetite, croaks at night, jumps and hides in cage.

She lives in a one gallon tank by herself (I know she needs a 5 gallon tank, but no matter how hard I try I can't figure out how to cycle my 5 gallon tank before she goes in it)
She is a heater, and her temperature is regulated by the heater.
I found out that yesterday my heater was unplugged for one day, so her temperature was room temperature, but it was only for one day so I didn't think that would be an issue?

I've attached a picture of her lump, you can't really tell how far the lump goes out but you do see how it is discolored. Please help if you know what I may be able to do to help her!
