The Oompa-Loompa Chorus, including Oompa-Loompas 1-5, can be as small as a handful of performers or as large as your stage and theater can accommodate. Consider casting your youngest performers as Oompa-Loompas (like the sixth grade chorus) and augment them with a handful of older students who can take the lead and serve as Oompa-Loompa wranglers.
