Snail is a party animal. Well...kind of. He especially appreciates the quiet things about parties, like confetti, using his indoor voice, and softly blowing out birthday candles. But parties tend to get pretty loud, and that's when Snail disappears into his shell. But not to worry! Snail still has fun at parties - it's just that from inside his shell nobody can tell he's having a good time. And this means he doesn't get many party invitations...So Snail decides to throw himself his very own quiet party. He plays hide-and-hide, he sways to his favorite lullabies, and enjoys a nice mug of warm milk. But that night, as he tucks himself in a blanket burrito, he starts to feel like something is missing. And that's when Stump, who's been there the whole time, chimes in with a suggestion. In the end, Snail realizes that he really does love parties, just not the rowdy ones. He and Stump put on their jammies, turn the lullabies down low, and "celebrate the shush" in their own quiet way.
