My Little Pony: Friendship is Magic, Season 8

Smolder:
[to Spike] If you're trying to hide, you need to do a better job. All I had to do was follow the smoke.

Spike:
[strained voice] Leave me alone...

Smolder:
What?

Spike:
[strained] Leave... me... alone...

Smolder:
I can't under-- Was that "sleeves made of foam"?

Spike:
[strained] I said leave [voice turns loud again] ME ALONE!

[He belches and blasts out flames, burning some brushes and mops to ashes and forcing Smolder to fly up to the ceiling]

Smolder:
[laughs] Wow! I have seen some pretty bad molts in my time, but yours takes the cake!

Spike:
Molts?

Smolder:
The molt. Super painful stone scales, fire burps, uncontrollable volume shifts - it's all part of growing up dragon. Congrats! [slaps him on the back, making him groan in pain] Oh, sorry.
