Me: What's this darling? It looks like a delicious biscuit. Did you make it in Kindergarten? Do you want to eat it this evevning for your "surprise" (aka pudding)
Him: Mummy! Are you crazy? That is Vogelfutter! (bird food!) We have to hang it up outside for the birds. It is stuck on a toilet roll. Do you want me to eat toilet paper?
I look more closely, it is indeed a squashed toilet roll inner covered in suspicious looking dried peanut butter and assorted seeds. Still does look quite nutritious though :-)
Me: Oops, sorry darling, let's hang it out for the birds then...
