Yup, tong feeding or feeding longer squirmier prey like earthworms etc is the way to go,.

I assume its the one-eyed toad who can't feed properly ??
I have a one eyed frog and he was fine at catching his food for about 6 months (He'd frequently miss but still gave it a good go and would catch food regularly)
however the older and bigger he got, the lazier he got & now can't catch anything himself.
Here's a vid I took of feeding time - Feeding Eyeball a cricket - YouTube

One other way would be to cool the crickets down in the fridge, then remove the toad from the tank and place him in a feeding tub.
This only works if the toads aren't easily stressed tho.
