In the show courage the cowardly dog was courage imaging everything?

I love the show courage a lot, one day I was on the iPhone app "ifunny" and it showed a picture of the episode "The great fusilli" with courage holding Eustace and Murial like puppets and it reads "This shows that Eustace and Murial are actually dead, and courage went insane and actually makes them think like there alive, and he also made us think that there alive"
I ask you
Is this true?

No because they died in that episode

I don't know but that episode scared me so bad.

The show is animated, so every thing resets at the end. If you watch some shows, sometimes the world blows up, or someone loses a limb, but the next episode acts like nothing happened. And, throughout the series, Eustace got killed or flung into space every episode and he still comes back the next week. Its just a cartoon. Hope this answers your question.
