Pac Man Frog Not Eating..

[Bor]

Try bathing him in a bath of 1 ounce Unflavored Pedialyte to every 10 ounces 80° dechlorinated water. Bath for 20 minutes then place the frog home in her water dish. Try and offer food after about 30 minutes later. If the frog is losing weight you will need to force feed.

Any tips on how to force feed? I don't want to hurt him.
