Plankton Party

Dive into the biggest party under the sea! You're a little voxel shrimp (or fish, crab, octopus, seahorse...) with a number on your tummy, and every plankton bobbing past on a party balloon has a number too. Gobble up anything smaller than you to grow bigger, steer clear of the hungry guests with bigger numbers, and zoom off when a giant comes chasing! Snatch pearls from golden showers, and if you get gulped, pop back out with a quick tip that makes you sharper next time. Eight worlds take you from counting to 20 all the way to fractions, decimals and numbers below zero. There are 30 trophies to win, creatures and bubble trails to collect, and you can party with up to three friends as one team against the bots. Who'll be the biggest at the party?
