The wood those wolves were made of wasn’t dry enough to catch fire?

Just imagine, you have a wolf made of wood running at you. Now imagine a wolf made of wood ON FIRE running at you.
 
Physical impact seems to be the best way to deal with them.

Are you implying that anything that spike sets on fire goes to Celestia? But in the last episode, Apple Family Reunion, Spike helped Applejack setting wood on fire, and it never warped to Celestia’s palace.

Well, that’s not what it’s about, BP. It’s about the quest

I doubt Celestia would’ve liked that very much.

Spike is a pansy. I thought we all knew that?

Because then he’d have already scary as it is wolves ON FIRE.

Because the plot said so.

Fear is the mind-killer, after all.
