The Keeper of the Boiler Room is a Green Puffle, found bouncing on the top-right speaker of the Night Club. In the book, Truth or Dare, a Penguin named RodgerRodger was dared to stay in the Boiler Room. He discovered a Green Puffle, the rumored 'Keeper.' He now sits on the top-right speaker of the Night Club, dancing.
The Keeper of the Boiler Room first appeared in May 2006.[1]
The Keeper of the Boiler Room moved to the Ice Rink in mid-July 2008 and hogged the puck all the time because the puck was temporarily glitched, and there were constructions in the disco, while building the DJ3K.
From March 4 to March 11, 2010, the Keeper of the Boiler Room went missing mysteriously along with the Keeper of the Stage, Rockhopper's Puffle (Yarr), and Aunt Arctic's Puffles. It was later revealed that these Puffles (and many more) had been trapped inside the Mine while Rory and other construction penguins were excavating the new tunnels. Later on the game Puffle Rescue was created in light of this.
Keeper of the Boiler Room has been replaced by many puffles during multiple parties.
In the book, "The Great Puffle Switch", The Keeper was mistakenly referred to as a female.
However, in most other instances, such as in a blog post made by Megg on February 27, 2016, as part of the Puffle Spotlight series, it is revealed that the Keeper of the Boiler Room is actually a male and not a female.[2]
During the constructions of the DJ3K, the puffle went out from the disco to the ice rink, and played with the black disk.
During the Music Jam 2016, the Keeper of the Boiler Room could be found at the Dance Club and the Forest at the same time after his task has been unlocked.
The second major plotline for Dancing with Cadence focuses around finding the Keeper after he mysteriously goes missing from the Night Club.
It is revealed that he was stranded when an avalanche trapped him and an unnamed yellow puffle (which may be Chirp) in a cave.
