Birthday Help

Soo my sons birthday is next month. He wants Sonic theme. He will be 5 Sooo I have been thinking a lot lately about what to do. I don’t think I’m doing anything for him big at home probably just get him a cake but just us. And maybe on the weekend take him out somewhere instead. I do wanna take something to his class so he can celebrate it with his little friends. I don’t know which option to do ? Get the class Sonic goodie bags. Or maybe pizza & drinks. ? Any ideas please
