When Eric Greenbogle wakes up on Christmas morning there are no presents under the tree - because Eric has been a BAD BOY! All he finds is a single bright orange satsuma. "I don't want a silly satsuma! What can a silly satsuma do?" But this is no ordinary satsuma as Father Christmas has given it magical powers. The satsuma springs to life and tries to show Eric that being bad is definitely NOT GOOD!
