Probably my favorite Gen 1 Eeveelution. It could learn Double Kick and Pin Missile in Gen 1 and while those moves have weak attack power, having diverse movepool in level up back then was rare.
Lapras is one of my favorite Water-types! Gen 1 has my favorite designs for the type in general. I think having it be based off of a dinosaur but not make it a Fossil Pokemon is kinda weird though. What's also weird is that I always use the one you can find in Union Cave in G/S/C and HG/SS, but...
Its voice in the anime is pretty funny. It sounds so overly seductive in Japanese and disinterested in whatever is happening to it in the English dub. :P I don't really care much for Goldeen in the games, though.
