Choose Goose is a talking goose who speaks in rhymes. He sells many various objects for adventuring or assisting Finn, but most of what he possesses either backfires or is, for the most part, useless. He has only said few things such as 'Hello my friends would you like something that bends? or a cat who makes rainbow scat?' 'Oh my a rat how indeed fat, hahaha!' and 'Do you enjoy my new hat? it was made by a cat! can i sell you a unicorn,or rather a narwhal horn?
