Annika’s almost 11, loves trees, and wants to protect them—but how? Enter the Green Squad! Together, they plan a tree-themed birthday bash with a twist: it's also a fundraiser for endangered trees like the majestic hemlock. From treetop trekking (even Eric faces his fear of heights!) to crafting forest-inspired decorations and creating “pocket forest” loot bags with real native trees, Annika learns how fun and impactful eco-action can be. She even meets a tree expert and gives her friends everything they need to start their own mini forests. With confetti, cake, and a whole lot of heart, this leafy celebration proves that even kids can grow big change—one tree at a time!
