It’s 10:00 a.m. on a Saturday morning in early June. At the foot of the Uetliberg mountain, several families are bringing the quiet forest of Uitikon-Waldegg to life. They're all taking part in a Topsy environment event as the lucky winners of a prize draw.
The kids quickly forget all about Mom and Dad. The first kids to arrive spot Topsy and run up to him. “High five, Topsy!” exclaims a little boy. “Can you talk?” asks a girl.
