(Urgent???) Problem with new White's Tree Frog

[bungusmash]

I just got this juvenile White's yesterday from Repticon, a reptile breeder convention. I recognized that it was small and skinny but figured this was just due to it being very young and didn't doubt the breeder's care. All seemed well, besides the fact that the frog (Boggle) has barely moved and is very sluggish, until this morning when I woke up and saw him laying on his back in the ledge's cup. When I flipped him over I noticed bright yellow bumps on him, which I for some reason did not get a picture of at the time. The bumps seem to have gone down a little but you can see the protrusion near the head and the bright yellow coloration on the toe in the third picture closeup. He is currently housed in the same vivarium as my other frog, but they are separated by a mesh fly shield. The only thing similar to this I've found on the internet is infected cuts, and I'm wondering if maybe he somehow got beat up, either by my other frog or on his own, and maybe the cuts have become infected? Besides that I have no idea, and I'm not sure what to do besides ask for help. Depending on the response this post gets he will be taken to the vet as soon as possible.

Sorry if the wording isn't great or something, I'm worried about him and I hope this can get worked out one way or another without my other frog getting sick.
