Clear slime and color change?

[spec]

I noticed when my frog was in the water there was some slimey stuff comming off of him. kind of look like spit in a way. and also perhaps its the part of his body that dosen't recieve much light, but around his back legs on his side it's yellow. he's pretty lime green. i'm thinking it's only visable after a good feeding.
p.s he has gotten alot bigger in just the last 2 weeks. twice the size of my avatar pic.

He's shedding his skin.

He's shedding his skin.

Is anything required of me?

No, he will probably shed every 2-3 days if you feed him well.
