Is our Pacman frog sick?

[xghostmakerx]

Hello, I am wondering is my sons Pacman frog is sick. He's been acting strange the last couple of days and only wanting to hang out in the water and he hasn't pooped in a week or so (that i can find). Yesterday when we took him out of the water to change it he made a sound for the first time ever. Today when I went in there to take him out of the water to change it, he stretched his back legs out and they were twitching a bit. He seems a little better now but we're still worried about him. He's doubled in size over the past month we've had him and he is eating with assistance.

I've heard of this red leg disease and he does have a little redish ting to his underside of his groin area. I am not sure if this is normal and I've attached a pic.
