Cultural References[]
The title of this episode is part of the phrase "Out of idle curiosity", which means to want to know something for no specific reason.
The ship slamming into the iceberg head-on and sinking with everyone on board is a reference to the RMS Titanic. Also, Lumpy looking for icebergs, ringing a bell, (similar to Frederick Fleet) and The Mole quickly changing directions (similar to Robert Hichens) similar to the sinking of RMS Titanic.
Sniffles retrieving the Idol and taking it to a museum could be a reference to Indiana Jones. The description for this episode titles Sniffles as "Indiana Sniffles".
Sniffles moving objects, like a bench and a soda machine, to block the door of the museum is a reference to The Blues Brothers.
