Just watched "Big and Small" on CBeebies ( *cough* ..um, with my son of course! *cough*) and was delighted to hear that Big collects plastic ponies!
http://www.bbc.co.uk/iplayer/cbeebies/episode/b00nz078/Big_and_Small_Series_2_Spring_Fling/ Big wants to do some spring cleaning.
Big: "If you help me clean I'll show you my plastic pony collection!"
Small: "Big, you're going to have to do better than that!"
Big: "OK...then...Oh! How about I give you a pony. Huh, Oh! You're very own plastic pony, Small!"
Small: "Fine then, deal"
Unfortunately you don't get to see Big's collection. They don't do the spring cleaning and get distracted having so much fun.
Small: "You still owe me a pony though Big!"
