Getting Fish to eat Fish Food?

Hey guys! I’ve gotten some great advice from you all so thank you very much for that. Now I’ve come to you again for your expertise!

So I’ve got this little goldfish, and I’d love to figure out how to make him eat fish food that’s dropped from the top of the screen. So far my little fishie can be moved with the arrow keys.

That’s it! Lol. Thanks much!
