I just use a smooth glass dipping sauce bowl or you can use one of your wife's expensive crystal candy dishes. It can be a couple of inches deep. Just push it down into the soil so it is flush. The glass is too smooth and the crickets just slide back down. The frogs will eventually wait for you at the bowl to put in crickets. You'll go through less crickets this way and you can be certain your frog is eating. Start off putting it close to your frogs soaking dish so he'll see it. Once he's used to it you can put it anywhere.
