The ice cream machine has gone a bit loopy so just catch each ice-cream scoop
that is flying around the parlour. Make sure each delicious scoop falls in the cone! Try not to waste any please. Remember, your ice cream order is only finished when it has a flake on top. Then give it to your happy customer.
