When a child is happy and active, his or her face gives off the radiating warmth of a racecar battery and the rosy sheen of a sunburned Englishman. Brighten your child’s cheeks with today's Groupon: for $15, you get two activity passes to Giggleberry Fair, located in Peddler's Village in Lahaska (up to a $29.98 value).

Giggleberry Fair melds the energy of an obstacle course and game room with hands-on learning activities such as puppetry, music, and more. Inside the towering play palace, kinetically savvy kids and parents jointly scale Giggleberry Mountain, a vibrant three-story, six-level obstacle course and maze ripe with thousands of foam berries and antioxidants. Slides coil through the space like a fraternal order of snakes, daring familial teams to dodge plush explosions of balls while maneuvering through tangles of nets. Bound into the game room, where the allure of skee-ball, Wheel of Fortune, and pinball light up kids with full-tilt excitement. Here, players retrieve tickets spewed from the mouths of skill games to redeem for prizes.

Tots age 1–5 can launch exploratory voyages in the Giggles Discovers! zone, a hands-on hoedown with interactive games, music, and a wooden replica fire truck. Two activity passes include unlimited rides on the The Grand Carousel, a restored 1922 showpiece that dazzles riders of all ages with its bold colors and brood of lonely hearts horses.
