Healthy Vs Junk Food is an educational video meant to show people how eating unhealthy can lead to long term bad effects.
The story takes place at a McDonalds fast food resturant, where Seth wonders to himself if he should eat the healthy, nutrious apple in his hand (which, weirdly, was not shown during the whole video), or McDonalds. He decides that, being an athlete, he should eat at McDonalds, but before he can, Merrick comes out and ambushes him. Merrick tries to reason with him, but it doesn't work. Seth goes in, though, and ends up getting "physically unready for the world" as a result. Merrick concludes by saying "and now you know. And knowing is half the battle!"
The only track that plays during this video is the first Mario Party instruction theme
