Children's Party Invitations

Information for the business: Child's birthday party invitation
Design details: I would like a child's party invitation designed. The party is a Pizza Party where the children will be making their own pizza to eat. The party details are:

11.00am on Saturday 21 November
Pizza Express, High Street
RSVP Louise on 07906 xxxxxx

The child's name is Percy and he will be 4 years old. I will be having the invitations printed by Moo.com and so they should confirm to the 'square flyer' instructions found on the Moo website here: http://www.moo.com/us/products/square-flyers.html

In terms of style, I want them to be fun and suitable for a party for young children. I quite like this design: https://www.tinyprints.com/product/64837/birthday_party_invitations_mamma_mia.html

However I'm not looking for an exact match.

Many thanks
John
