"Traditional maracas consist of hollow balls made from dried gourd shell (cuia "koo-ya") or coconut shell filled with seeds or dried beans and mounted on a wooden handle."
Huh. I thought they were just wood and sand or beans. Learning things.
"Maractus appears to be based on a flowering cactus, most likely the prickly pear, and a maraca. It also physically resembles a rabbit and may be a visual pun on the bunny ears cactus. It also seems to be based on traditional Mexican dress styles and, due to the fact that it dances and makes maraca-like sounds, may be based on Spanish dances, possibly the Mexican version of the Cuban Son."
Huh. I knew what a prickly pear was, because...Banjo-Kazooie, but I didn't realize Maractus was one.
