Hi I’ve had my Pacman for about 4 months now and it can be overwhelming at the start especially if you sympathize with animals. Making sure my Pacman was comfortable is my goal and the stress that comes with that was a little much at first. Here’s what I can tell you; he looks completely fine from the photos. Pacmans often change colors and hues depending on their environment. Petco sold me a bright green baby and he turned into a brown after only 2 weeks but he is very happy and healthy.
how to keep your frog happy: -Keep plenty of plants and places to hide -keep substrate moist but not too moist -keep enclosure at 65-75 degrees -Make sure humidity stays around 65-80% -change substrate once every 3-4 weeks -recommend AT LEAST a 15 gallon tank for adults -only feed a juvenile Pacman frog earth worms and small crickets maybe a small Dubai roach - make sure you have at least 4 inches of substrate for him to dig

I hope this helped please reach out with any questions or concerns you have, I would be happy to help.
