Can a Pokémon suddenly sleep for no reason?

Question

So, in HeartGold, at route 21, I used my level 66 Dragonite and used Outrage to beat a swimmer's Quagsire. Then, my Dragonite suddenly sleep for no reason. Is this just a glitch or a feature I didn't know of? (I already had 16 badges)

badges* it almost looks like you're saying badgers. :3

Answer 1

Well, the only logical reasoning from this was that the Quagsire had either outsped your Dragonite, or survived a hit from it, and then used the move Yawn. This would cause Dragonite to get drowsy, and then the next turn, fall asleep.

He probably wasn't paying attention to the game and just spammed the A button.
