The Sea Lion Pokemon. Seel shows up late in Yellow's Seafoam Islands. Worth grabbing if you need a Water/Ice type, since Dewgong is a solid C-Tier pick.

Is Seel Good in Yellow Playthrough?

Seel doesn't hit hard from either side and is slow to boot. The evolution into Dewgong adds Ice typing for Lance, which is about the only reason to consider catching one.

How to Get Seel in Yellow

Seel packs into one icy area, 4 encounters in a single location, rare-to-uncommon. The whole population sits in that one cave, so you won't be hunting it across the map.

Encountered via tall grass encounters

Badge 5

Where To Catch Seel in Y

Seel is the chain's first catch. You'll find walking and trade encounters from Lv. 22-34 across 7 total spots in the chain.

Bring the right balls: check Seel catch odds in the Yellow Catch Rate Calculator before you throw.

Seel Weakness

Y Seel Best Moveset

70 Special behind Water moves that can't compete with Lapras, Starmie, or any of the top Water-types even at full power. The Ice typing arrives with Dewgong, where the stats at least function. Nothing competitive happens before evolving.

Moves List

Most of Seel's flexibility comes from TMs. Same-type output runs through Surf and Bubble Beam, but Normal and Ice and the rest of the TM pool push it from predictable to genuinely threatening.

Seel Yellow Guide

  • In Yellow, for a casual playthrough, Seel works as a placeholder. Water coverage is useful early. The real payoff is Dewgong. That's where the stats start mattering.

Game Availability

Present since Red & Blue, Seel appears in 19 games spanning 9 generations. Gen 1 originals like Seel have the longest track record of availability in the series.
