Mr. Peeple, the leader of the humans, will stop at nothing to drill for oil even if it means destroying Meropolis.

Mike, a small citizen of Meropolis, must learn he's big enough to make a difference to save his city.

Daring break-ins, shooting sea stars, mermaids the size of blue whales, and seaweed wrapped pizza, all lead to an exciting adventure that you don't want miss.

Will Mike halt Peeple's progress or will he be left in ruins?
