My toad acts very similar to your pacman, but it's not afraid of me which I guess helps.
What I normally do, is pick up my toad (out of it's terrarium), set it on the floor, (yeah, the floor) and put a food item in front of it, the second it moves, the toad strikes and eats it.
I've tried feeding it with tongs/plastic tweezers, etc. but it just isn't interested, by putting it on the floor, it's gets "exercise" as it occasionally hops around, and it's food can't escape anywhere, also, you may find it helps if you get a large flat rock, and put it in the terrarium, then drop insects on top of the rock when the frog is near/looking, they can't borrow anywhere, and the frog can strike them eaiser on a hard surface, I use that method when feeding my toad grubs.
Hope it works for you!![]()
