You guys always have great ideas so thought I'd pick your brains!

DS is in kindergarten. I signed up to help with the Easter classroom party and my responsibility is to come up with a game/activity.

An activity can be a game or a craft activity, or anything smart (and easy). I want to do something super easy that I don't need to buy a lot of gear or prep for days for 15 sets of crafts.... if I don't have to . Also the teacher doesn't like the idea of "gift bags for everyone". She said a prize would be ok if needed - I imagine if someone won in an activity they'd get a price. I have 5 Easter pop-up books that I can give out, so I am leaning toward an easy game, and giving out the 5 books at the end (There are 13 kids in the class though... I can get extra knick knacks if I have to - thoughts?) . DS told me at Valentine's day party they did Bingo, which is easy and simple and great.

I was googling for ideas, and something like this egg toss game would be ok, but then the logic of how the prizes are going to be given out would be a problem:

Any Easter craft ideas would be lovely too. In general I want to stay away from something messy or something that requires everyone to be dancing and running and such, as I don't want to trouble them to move tables and chairs away ...etc. And they would have already had an egg hunt earlier in the day.

I can't believe I am stressing out about this... haha. Any other ideas would be lovely!
