When Sonic heard Tails was going to be experimenting with body weight he didn't think the fox would experiment on himself.

"UROOAARRRRRPP!!... Ugh.... That one was left in there too long."

Tails was always a little guy yet now he was a good 550lbs with thick enough thighs and a large ass that could cover two seats at once.

His belly was a flabby marshmallow pile of fat that stuck out from his body with a few rolls that showed the fox had been eating.

He had developed a set of b size moobs that almost made him look a little female like.
