Hastily written on 5yo’s Santa letter - crossing out ‘all the Batman lego’ and replacing it with ‘a littul bit of Batman Lego’ to make space for it! On questioning, he apparently means ‘a toy gun what fires sweeties instead of bullets’ (phew).
The only one google gives me is just a water pistol with sweets in the reservoir. It doesn’t fire them.
Has he seen this on a cartoon maybe? No idea myself!
