The sweet Blops are friendly aliens that are visiting Earth. As their spaceship was orbiting our planet, and while they were flying out and about searching for resources, they lost altitude due to the pollution coming from earth and fell to the ground.
Help the Blops regain their flying capabilities to fly back up to their spaceship by directing each Blop to eat the same-color cookies raining down on it from the Blops spaceship.
When was the last time you spotted a Blop in the sky? Can't remember, huh!
Well then, Welcome to the world of Blops, take care, a Blop can't fly up too high, it can't survive in the thin air.
