The game currently includes four helpers: Winston the bulldog, the Black Cat, Polly the parrot, and Horace the monkey.
Helpers assist you with levels by tossing a booster on the board. To get aid from a helper, you should fill the bar under the helper during a level by collecting gems of a specific color. Each helper has their own booster and color. Helpers are active for a specific amount of time, such as one hour, and are displayed in the window that appears before the level starts.
