Pac-Man did not eat crickets

[monster]

How big or old is your Pacman frog, or how long have you owned him/her? What is the temperature and Humidity in the tank, and how big is your enclosure? What are you using for water and substrate? When was the last time you found poop? There is more questions but if you could answer these few they are very important factors for his health and digestion. Oh, and what kind of pacman frog do you have? Do you notice anything off in his appearance? for example does he look like he has any lumps sticking out of his sides or does he looked swollen/ bigger then usual. And if he just having a hard time catching the crickets you can try ripping the back legs off so they cant jump.
