Unikitty and the gang gear up for a fun day at the beach, but Master Frown uses his position as lifeguard-in-training to spoil their plans. They embark on a beach quest to find the legendary Perfect Spot, far away from Frown's tyrannical rule. Though Master Frown and Brock are not far behind.

Richard finds the opportunity to take the others on a road trip, but soon the road trip turns haywire with bathroom breaks, stops to fix the tires and the van itself, interdimensional space/time travel, crumbs, road rage worriness, and an "evil truck" (in a reference to Duel).

The gang arrives at Doki Diamond Funland, their favorite amusement park to ride the life-changing ride called The Sugar Crash. When Master Frown arrives to get everyone out of the line, Unikitty and the gang try and stop him.
