For your next adventure, design a dungeon based on a Children's Day open air event!
Petting Zoo: You are in a pit. 2d10 Huge creatures are trying to aggressively pet you.
Face Painting: Roll Dex and Athletics to paint the required symbols on a Small moving target.
Bouncy Castle: Enter a swarm of Raging Small Creatures on Difficult Terrain. Good luck.
Candy Booth: Your Small Creature now has 1d6 hours of unlimited Dash actions and Bardic Inspiration.
@TarkabarkaHolgy Facepainting if you are not doing it yourself is a patience driven skill the DC determined by getting to the painter when setting up, but also expectation managing whether or not they'll be able to make the child look like a dandelion-robot.
