The Bash Splash is a party held by Bash Johnson every year at McFist's mansion. The purpose of the party in the episode House of 1,000 Boogers was to discover the ninja's secret identity using snot samples. One of the games that were present at the party were the McFissues. Randy and Howard crashed the party by sneaking in with Bash mark disguises, which were simple punch marks on their arms. Only students with the Bash mark were welcome to the Bash Splash. The party was evetually destroyed when Howard, Bash and his friends fell from the very high diving board causing a massive wave from the pool.
