Purple Car
Our child (not yet two) has a little car tower toy with four coloured cars. The purple one has gone missing. Catastrophe.
It's the first thing he has lost and really cared about, and the whole family have spent a few days checking underneath every piece of furniture, looking in every cupboard, searching all the toys again and again (and again and again...) to no avail. All while he repeatedly said "pur-el? pur-el?"
So much for context: I had some spare little bolts and washers, and I sawed some wood down to size, and painted him a replacement.
It's a bit of a rush job, but that just means opportunity for a Purple Car 2.0 (3.0) with some better materials.
