What is that in Fire Cracker's Playdough?

I am not sure, but I seriously think there is a limit to the number of things you can find in a 2 year old's playdough. I mean Crayola makes plenty of kits with tools and toys for playdough. Of course Fire Cracker does not prefer to use those, of which we have plenty. He prefers to use his own creativity. I love that he thinks "outside the box"! At least he knows not to eat the playdough. The downside is that he likes to feed the dogs playdough! Here is a list - no joke - of the things I/we have found in his playdough since Christmas morning. They are not just on the playdough either, they were embedded in the playdough!

1. lego(s)
2. miniature race cars
3. the motor for Smoke Bomb's Snaptricity set
4. the connectors from Bottle Rocket's Snap Circuit set
5. the lid to a bottle of water
6. the lamp socket for Snaptricity
7. a whistle
8. crayons
