tell me the favorite things you’ve gotten in goodie bags at kiddos birthdays!

my daughter birthday is coming up in August. i want to put things in goodie bags that’ll be of actual use to the children / parents.. instead of just things that take up space and get thrown away. what do you guys usually do for goodie bags or what are some favorable items you’ve received?

it’ll be outside at a water park and it’ll be hot, so whatever i put in the goodie bags need to withstand the heat!
