Trivia

 * For some reason, Snowfield Gelzol have their name reversed, but are otherwise unchanged aside from their strength.
 * These are one of the few enemies to be a direct reference to an enemy from the main Zelda series, namely the very similar Zol and Gel monsters. Whether the creatures are directly related or simply share a similar name is unclear, but given that the Tingle games appear to occupy their own canon, it is likely just a reference.
