uhhhhhh, they are nocturnal so jumping around, kicking dirt around in the process and squeaking their feet at the bottom while they try to burrow are all NORMAL behaviors for an active pacman frog. I dont think hes thrashing around becasue he is upset about being fed mid day. If he eats, he isnt stressed out about being woken up, if he were stressed about being woken up he wouldnt eat...
The reason it is suggested to feed at dawn or preferably dusk is because this is when they are most active. Feeding them in the day time is not going to damage your frog.

Hes moving around in his cage because he is awake and active, obviously.

The poop, yes. That will make them move about becasue once they drop one they want to get as far away from it as possible. and they way they lay them, I dont blame em. Whenever I hear activity in an enclosure i dont normally hear activity in, I know theres a turd about.
