Owl

The Owl is a critter that only serves as environment flavor and spawns on the surface Forest during the night. Due to them having only 5 HP and no defense, they are often killed instantly by enemies or the player itself.

It can be caught with a Bug Net to be carried around in the inventory and released later, or crafted into an Owl Cage to be used as furniture. Once crafted, the caged owl cannot be released again, and when placed down it moves around inside the cage as it would do outside.

Trivia

 * Much like the duck that has a human voice say "quack" as a rare easter egg, the owl has a 1/300 chance to make a human "hoot" sound.
 * Seeing Owls flying may be confusing because of the Demon Eye that spawns with an owl costume during Halloween looking similar to a flying Owl.
