yellow shapes for red/blue Tupperware Shape Sorter anyone?

[TaurielTest]

A long shot, this, but...
I boughtan old-school shape sorter like this from a charity shop. My son LOOOOVES it. It only has eight of the ten shapes (is missing triangular and hexagonal prism!) and the cylinder one is badly chewed.
If anyone might have any of the shapes lying around, it would be wonderful to complete the set. Happy to buy/make a charitable donation/swap for something you might need. Can anyone help?

I do have one of these somewhere-the problem is I have no idea where but you could also try tupperware as they have a lifetime guarantee and you have a badly chewed piece.

alas the warranty is for the USA - and I'm not sure how far I'd get with my charity shop receipt anyway

this is from the tupperware uk site.

If I have lost a seal or any other part of a product, can I buy a replacement?
