I realized that I forgot to post about the Percy Jackson party we threw months (years?) ago when the movie was coming out! Oops! I am posting it anyway because we had a lot of fun, even though I was the only girl there.

True story: I was drawing the tongues on the heads when this middle school boy walks over and says "Nice hydra" all nonchalantly! He did that whole appreciative head lift too. If I remember correctly, I looked at some hydra coloring pages on Google Images and then used that as the basis for mine. If I had to do it all over again, I think I'd have cut the
If you're more comfortable tracing, you could print a coloring page onto transparency film (I just put ours through my regular printer to make a mermaid for the 2010 summer reading program).

We did several ideas from the Percy Jackson event planning kit. I also put together a PowerPoint Monsters game, where I put an image up of a mythological creature and the kids raced to name him/her/it. Unfortunately, I can't find the file for that. We also did Percy Jackson madlib game (download). I think the idea for that came from PUBYAC.
To promote the party, I put a book display out with our flyers (sorry, no file for that anymore either!). You can download the sign I made to go with it though.
