Day 13: Riddle Me This

Yesterday's (apologies for lateness) prompt was to write a riddle, so here is a riddle based on a game. If you know the game you'll get it straight off, but if not, comment with your answers! I'll give you something nice if you get it right!*

***

Ladies and gentlemen, riddle me this

What is the rule that allows things to fit

Into Happy Valley, the nicest of places

Where folks wander round with great smiles on their faces

Well, actually, not smiling, but grinning instead

As they gobble their dinners of focaccia bread

There are no dogs or cats, but puppies and kittens

No coats or scarves, but wellies and mittens

And despite what you might think, there are villains and baddies

Who weren't taught to behave by their mummies and daddies

But generally it is a carefree place

With no disasters or wars or invaders from space

So tell me at once! Do not dilly-dally!

What rule must you abide by to enter Happy Valley?

*I'm not going to lie, the nice thing will probably be a poem...
