Stella, Sam and Owen are packed and ready to go on a picnic adventure. But an unexpected thunderstorm ends the outing before they've even left the house. Not wanting the bad weather to cancel their plans, the kids decide to go on an indoor picnic.;

Sam is fascinated to learn from Stella that the dragonfly perched on his shirtsleeve is really a baby dragon named Sparky. He's disappointed when it suddenly flies away. A search reveals hundreds of other baby dragons playing hide and-seek with Sparky.

Sam gets frustrated when his fort made from chairs and a bed sheet falls apart. His mood quickly changes with an offer from Stella to build a snow fort. While scouting for a good building site, Sam remarks on the cold conditions that animals must endure.
