These amphibious, rubbery little frog creatures are native to Tatooine and can frequently be found hanging in market food stands.
Many aliens and humans on Tatooine enjoy these little delacacies. Jabba the Hutt has been seen chomping on them before. Jabba also likes paddy frogs, which are similar to Chubas.
