Toys & other items for 2 - 3 year old boy. (Aldwick PO21)

Toys for 2 - 3 year old (~ 20 kg) grandson visiting me from abroad for several months. He partcularly favours plastic cars, toy trucks & diggers, or things he can ride on. Anything that will keep him occupied in the house or garden, or items such as a potty would be most welcome, as he won't be able to bring his own things with him.
