Some event parameters need research

Animation events control functional events synchronized to rigged animations for things like sound effects, visual effects, character messages, and playback control. The events can be found in different places in each game; in Prime 1, they are stored in their own file format, the EVNT format. In Echoes, the format is the same as Prime 1, but was merged in to the ANCS format instead of getting its own file. In Prime 3 and the Donkey Kong Country series, events can be found in the CHAR format, as well as Prime 3's SAND format.
