So I made one up as I went. I was originally going to have the wings on the back and the sleeves would be Toothless' front legs, but the little guy wanted wings he could flap with his arms and I realized that was going to be way easier to do, so we went with that... The 'top' over laps in the front and does up with a bit of velcro at the neck. The tail goes on like a belt and again does up with velcro. Once Toothless was finished the little guy requested his sister be Stormfly, but that was just a bit beyond what I was willing to do, so we rummaged through the little miss's closet and came up with an Astrid costume instead.
On party day we set up a shield decorating station where the kids could decorate their own shields. This was good to get the kids involved in something as soon as they got in the door, and also kept them busy while waiting for the other dragon trainers to arrive. I pre-made the shields from cardboard, tape & ribbons so the kids could hold them on their arms. We just put out our stock of coloured pencils & markers and the kids loved it.
Next the kids needed to earn a sword to go with their shields, so we played pin the tail on the Toothless. I had planned to make swords, but then I found some inflatable ones for $1 each and figured there was no way I could make anything for cheaper, and they were nice and safe to be played with even after the inevitable sugar rush. Everyone got a sword, but they were handed out in order of who got Toothless' tail closest to the right spot.
After a bit of sword fighting mayhem, we played another game... Feed the Gronckle. Every good dragon trainer knows that gronckles eat rocks, so I made up some rocks out of scrunched up newspaper covered in tape. I printed out a picture of a gronckle and stuck it to a large box. I cut out the bottom of the box and also the mouth of the gronckle, and the kids took turns throwing rocks into the mouth. It was great fun, and the kids kept going back to this one throughout the party.
And then one last organized game before cake time... It was our own little version of sheep racing.
The kids lined up into two teams and took turns putting a sheep pom-pom between their knees and delivering the sheep past the line placed at the other end of the room (without using their hands). If they dropped their sheep they had to go back and start again. Again, lots of good fun and the kids really worked together to help each other out with this one. It was pretty much impossible to get a photo of this one, sorry... But then there was cake, a fire breathing cake even!
The party finished up with opening presents and then running around the deck and more sword fighting - fortunately the hanging balloons were a favourite target.
