I would run some experiments on the variables mentioned by Scott^. See if changing humidity, lighting, noise, etc. See if changing anything helps. Do they have enough stuff to climb on in there? Maybe they are bored. Dumpies are active at night, and without enough things to do like climb, hunt, proper mating conditions of they are a pair, they could get easily restless. These frogs are a lot more pet-like than most other tree frogs, so you should treat them that way too, and give them sufficient attention. My dumpies are as happy as can be, as I handle them and hand feed them everyday. Heck, my adult perches on my shoulder for sometimes hours at a time while I do my homework! He's even "potty trained" to get it all out when I run him under the filtered water faucet over the sink. So funny!
