Izzy is always shuffling, jiggling, squirming and twitching. She just can't keep still! So when Izzy's school go on a trip to the zoo, her teacher warns her to behave. She must never wriggle, she must never fidget and she must certainly NEVER TICKLE A TIGER! But does Izzy listen? She does NOT - and what happens next throws the zoo into complete chaos.
