It's Past Your Bedtime!
From SmashWiki, the Super Smash Bros. wiki
It's Past Your Bedtime! is a single-player event match in Super Smash Bros. for Wii U. This event is set on the Gamer stage, with 5-Volt existing as a stage hazard. The objective as the player controls Jigglypuff is to make Ness, Bowser Jr., and Toon Link fall asleep by using Sing; the event is completed when all three opponents are asleep at the same time. The opponents all stay asleep for far longer than in normal matches. Bowser Jr. appears to be more aggressive than Ness and Toon Link, as he will sometimes attack the player using any his four special moves, while the other two will generally just avoid the player. If an opponent reawakens, they must be put to sleep again.
This event is unlocked by clearing Playing Tricks. Completing the event does not unlock any additional paths.
Completing the event on hard difficulty awards a Thistle Jump X Defense equipment.
