"You’re just a little blob from space (as the title suggests), who has landed on Earth with all your blob friends. Upon your arrival, you are immediately incarcerated by what appears to be an evil genius/mad scientist type. As you may have deduced, the game is about escaping from the mad scientist and saving your blob amigos but with a few additions and progressions along the way. As a blob, like other blob fiction, you can absorb and eat things… well anything, really… as long as you’re big enough. When you’re small, you absorb smaller things to grow bigger, and then absorb bigger things and so on and so forth. You clear levels by jumping or squeezing through obstacles and becoming big enough to bust your way out of there."
