Grumblies are interactive creatures that react when you poke, flip and shake them. The more you mess with them, the Grumblies they get! Poke a sleeping Grumbly in the belly and you’ll startle them awake. Keep poking and there may be gassy consequences. Flip Grumblies around and upside down. Warning: May cause dizziness, belching and tossing of cookies. Not grumpy enough? Time to shake things up. Shake Grumblies back and forth to send them into hysterics. You can also try rolling, juggling or smacking Grumblies. The only real rule is don’t follow the rules!
