Thankfully, the injuries weren't as bad as they looked. It didn't take long for most of his injuries to be healed when he was taken into the Pokemon hospital, and it was probably a miracle that none of his bones were broken, since if he were a pidgey, being squashed by a Venusaur would have meant death; Zapdos would have to thank for the legendary status and being a fairly large bird.

Although, it must have been such a weird sight for those at the Pokemon Center to see a Venusaur to drag in a Zapdos...
