If you want to make a cool birthday party with a knight or a dragon theme, you can serve cool dragon 
eggs.
The dragon eggs can be made a few days in advance, so you just have to serve them at the party. But make sure they are stored cool and dry!
They look really cool if you apply them to a dragon nest cake (and then you only have to make a few dragon-eggs). The guide for that + lots of other ideas for a knight party can be found on this page.
Just follow the step-by-step guide to see how to make them 🙂
