The Waterballoon Egg is a contract-only egg in Egg, Inc. It was added in version 1.7.5.

It is one of the two Summer contract eggs, the other being the Firework Egg. Similar to the Easter Egg, it has an abysmal value, making it harder to get a large profit fast.

The egg was invented as yet another way to turn things into egg form, this time for waterballoon fights.


The Waterballoon Egg appears identical to a normal waterballoon, having a salmon transclucent 'shell' with a tied-off top and almost completely filled with water.
