Finally the weather was warming up! The Willow swayed contentedly in the breeze, happy to be rid of the winter chill and ice weighing its limbs down. It stretched its branches to soak up the precious sunshine when...

Wait, what's this? The tree felt a strange sensation. Something was tickling its roots!

GET IT OFF! GET IT OFF!!!

The Willow thrashed its branches about wildly, trying in vain to stop the uncomfortable tickle.
