The finch is the main character of Cooped Up.
The finch has a green coloured body and wings, two small eyes and a small tuft on its head. It has a stomach slightly sticking out with small wings next to it with a pair of small claws.
The finch will jump to the next string above it after the player releases the finch after choosing an angle. The finch will immediately fall off the screen after making contact with a rival finch or a falling item. If the finch manages to eat ten bugs, it will be boosted upwards past ten platforms and gain ten points, knocking off every rival finch and passing through every hazard until the effect wears off.
