Someone needs to have a word with Trading Standards. It's technically shot rather than shell, and if it's shot it shouldn't blow up!
Are you telling me you haven't taken him yet? Appalling. (In truth, about Seven is the right age. Morning: "I don't want to see the boring tanks. That sign says Monkeyworld. Can't we go to the beach again? Afternoon - manic look while wearing a US lid - "This is the best place ever! Can we come tomorrow?")
For reference. A terrible place called Monkeyworld does indeed lurk nearby. It draws in knowlessmen and the weak of will. Never go there. Stay on the true path. Do not weaken or compromise. It is a price not worth paying.
