** “The Adventures of Commander Crumbcake, Vol. 1: Revenge of the Words.” Hi-Tops. $14.95.

Aimed at the 5-to-10 set, this is an educational video about antonyms, synonyms, suffixes and prefixes. In two half-hour episodes, Crumbcake the superhero dog cracks an antonym code and stops CREEP (Collection of Really Evil, Evil People) from creating worldwide chaos with phony dictionaries. The informative moments work well, particularly a humorous segment about a thesaurus salesman, but the action drags and a couple of grammatical errors have slipped by the editors.
