Plaster of Paris
1 Large Punch Balloon
Green Crepe Paper
Felt (Light Green and Black)
Tape (I think I used Duct because I couldn't find the painters)
Styrofoam Cups (Ears, Eyes, Nose)
Glue (For the felt)
Crown - Found that foam shape at the dollar store
Oh I had also planned to make Angry Birds masks for the kids to wear while they beat the living daylights out of this Pinata, but only managed to get one done in time so I scrapped that idea. If you get time to do that it's really cute and plays into the whole theme really well.
Depending on what you already have at home, you can get this done for well under $10 bucks!
(The head looks kind of caved in on the right, it wasn't. Just a weird angle of the photo)
