3rd Gen Keckleon and Snorlax

In Hoenn, several invisible Keckleon are found around the vicinity of Fortree City. In Kanto, two Snorlax sleep on paths north of Vermilion City and west of Celadon respectively. Both of these Pokémon block the road until the player finds an item to make them move, after which you engage them in battle. Did you try to catch these Pokémon or just faint them? Did you actually end up using them on your teams at all?

I caught Snorlax, Keckleon, and I have used them both in battle.

I caught Snorlax and Keckleon, but I haven't used them in battle.

I didn't catch team, because on that time my party was full and also there is no use to keep them on PC ( not pokecommunity).

Nah! As i said earlier my party was full, so i can't catch any pokemon after the event.
