need help with my little guy

[Sheldon & Tori]

hey everyone, i think my little guy had a siezure but i don't know for sure.....he started flinching his front legs, then he hopped twice, and then he started shaking. after he stopped shaking (about 5 seconds later) he just sat there for a couple minutes and then started hopping like crazy. i just checked on him and he is sitting in his water dish doing the "pac-man thing" (not moving). his enclosure is nice and damp, and he has a heat pad and a heat lamp keeping his temperature around what i was told he needed. i know this siezure-type activity isn't normal but has it happened to anyone? or can anyone tell me what may have caused it? Tori and i are a little worried about him.
