Ultimate Weapon

Max’s Plumber equipment detects that an ancient mask had been unearthed in Texas. This quickly triggers a change in Max’s attitude; he claims that this artifact would lead to the most powerful weapon ever designed, and that he should retrieve it before it falls into the wrong hands. Max immediately becomes more impatient, worse-tempered, and far stricter. Upon retrieving the mask, the Tennysons come into conflict with the Forever Knights, who want to find the weapon themselves. The Tennysons end up with the mask after a struggle and use it to find the ultimate weapon, the Sword of Ekchuah, inside of a Mayan pyramid.
