Poor Nundja! He’s always tired and walks around yawning. The other Knomes scold him and call him lazy, even though he can’t help it.

One night the evil Tiger King steals “The Knomes’ Heart” ruby from The Knome Village. Three brave Knomes are sent off on a mission to get it back ... and to everyone’s surprise Nundja is one of those chosen!

Now the sleepy Knome goes on an adventure of a lifetime - across Carnivore River, down through Spider Valley and to the Tiger King’s fort. But when the other Knomes are captured, Nundja must wake up and find a new side of himself to save his friends and reclaim The Knomes’ Heart.
