Two very small friends who have huge adventures. Ula and Hop are miniatures, small beings that live secretly among us. This time, Ula and Hop sneak into Dani?s backpack and show up at his school! Did you know that in every school there are classes of miniatures? But they go to school to learn salamander taming, how to fly in paper airplanes and a ton of other nutty things. Can you imagine all that you could do with friends that fit in your pocket?
