Sleepover

A sleepover (also called a pajama party or a slumber party) is an activity that the Smurfs occasionally engage in, where Smurfs could stay up all night telling stories and playing games with each other until they fall asleep.

In the EMPATH: The Luckiest Smurf story "The Fear Of Smurfitude", Dreamy took the liberty of inviting Hefty, Jokey, and Tapper over to Empath's house in order to have a sleepover so that Empath could feel comfortable sleeping in his new house, and also to find out what's causing Empath to have terrible nightmares.
