What I like about Ikea merchandise is that it encourages imaginative play.
When Fai first saw the blue chute, he got Han to sit inside and he dragged his brother around.I think that takes a lot of trust, to sit inside, not knowing where you will be pulled to.
They took turns pulling and being pulled.
When Han lost interest and went to play camping with 2 bunnies, Fai turned into a caterpillar.
What a workout he got.
