Lapras, the Transport Pokemon

Everybody loves the Loch Ness monster! Here's a beautiful build for the blue beast!

Whirlpool
Perish Song
Rest
Thunder

IVs: 31 HP, 31 Defense, 31 Sp. Defense
EVs: 24 HP, 252 Defense, 232 Sp. Defense

You want the Dream World (DW) Ability Hydration for this build. The big idea here is to trap the opponent with Whirlpool, then follow up with a Perish Song that they cannot escape! Just be sure to withdraw before the Perish Song count is up or you're going down as well. The other moves make him capable of tanking in the Rain. Rest will provide healing without the 2-turn sleep, and Thunder will never miss, and will have the 30% chance to Paralyze the target. Rain will also add to Whirlpool's initial damage, which is nice. For an item, good options would be a Leftovers for healing purposes, or a Binding Band to double the damage Whirlpool does over time (from 1/16 per turn to 1/8 per turn, and Whirlpool lasts 4-5 turns).

How do you get this elegant trapping tank?

(1) Teach a male Piplup Whirlpool by level up (lv 32) and Rest through the TM. Breed it with a female Lapras that has its DW Ability.
(2) Aim for a Bold Nature. You want the Hydration Ability for this build, but if you do not have access to it, aim for Shell Armor, and definitely hold the Leftovers over the Binding Band.

So there is Lapras, the Pokemon that understand human speech. A flaw to this is other trappers trapping you into your own Perish Song. If you have any questions or comments feel free to comment below.
