When I was a kid my mother would tell me over and over, “no Hot Wheels cars in the bathtub”. Nowadays it’s actually encouraged with sets like the Hot Wheels Race Rally Water Park Playset because it floats! This set has 2 ramps to send cars twisting down in a race to splashdown into the water. Comes with 1 car. You could also use it in the pool (or kiddie pool or more preferably a kiddie “ool”, there’s no p in that one). What will they think of next?
