My son has been playing with Early Learning Centre Happy Street for 2 years, ie since he was 18 months. Ages ago we lost the Rescue Helicopter when we were out somewhere, and now as he's old enough for detailed imaginative play he keeps saying he wants another one. I don't really want to buy the whole Rescue Vehicles set, but I do have a spare digger, roller and dump truck (all with drivers) from the Happy Street Construction set and wondered if anyone had a spare/unwanted helicopter to swap for one of the construction vehicles?
