Jeff tends to fall asleep a lot, which causes the others to call out "WAKE UP JEFF!", and that causes Jeff to jump up and down and do all sorts of silly things.
Jeff plays a variety of key instruments such as the piano, keyboard, accordion, and occasionally other instruments like drums or guitar. Out of the original generation, he sings the least, only having a few lead songs like Would You Giggle, I'm a Cow and I Just Can't Sleep on Christmas Eve.
