Whilst I don't think this little guy is particularly good looking, you could modify this Pinata* tutorial to include any ideas you might have such as a giant pumpkin for halloween or a giant heart for a wedding. The "pull the string" bit is the important bit and details of how to make this bit are right HERE at thingamababy.
* I only found out what a Pinata was this year when I attended a 1st birthday party. They are really cool and different for parties and events. Read all about them HERE.
