When Liz invites the Critter Club girls to her house at Marigold Lake for the weekend, they are really excited for their camping adventure—especially because Marigold Lake is known for having lots of wildlife! While the girls are there, they plan to do stuff like swim and canoe in the lake, go on a nature walk, and camp out. But with every activity, something seems to go horribly wrong. Amy accidentally tips over the canoe when the girls are out on the lake; Ellie gets spooked by what she thinks is a snake on their walk; and Marion is not pleased about sleeping outside in a tent. Liz thinks her friends aren’t having fun, and she starts to feel awful. Will the great weekend she planned turn out to be a disaster?
