Toad Needs Some Vitamins

Toad Needs Some Vitamins is the second episode of the sixth series of Toad Meets World.

Plot
The reason why Toad hasn't changed a bit (mainly his voice) is because he isn't getting any vitamins. At all. His parents tried forcing him to eat fruits, vegetables, and eggs, and drink milk. But he wouldn't listen, being the stubborn little b-tard he is.

One day, Toad was going for a walk, when he suffered a heart attack. When he was at the park, he suffered brain damage, seizures, and narcolepsy, and remained this way until an hour had passed. Then, Puff the Magic Dragon comes along and consoles him, saying, "If you want to live, you need a lot of vitamins and minerals to help you remain fit and healthy!" Toad now realizes he needs a great deal of nutrition for his parents', for Puff's, and for his own sake.

Moral
This was (subtlely) stated in the episode by Puff.
