The Explorer's Club is a group of explorers from the Ninjago: Masters of Spinjitzu animated series.
The club operates out of a building in Ninjago City, which serves as both a gathering place and a repository for various artifacts. The club also maintains a private force of uniformed security guards.
Cecil Putnam (voiced by Paul Dobson) is the current head of the club.
In "Booby-Traps, and How to Survive Them" Cecil calls Clutch Powers to inform him that his membership in the club is being revoked. When asked why, he notes that Clutch hasn't done any exploring in over a decade, which is against the organization's charter.
