The Chansey featured on this page recreates the Level 1 Chansey distributed during the Happy Birthday! event for Pokémon Let's Go Pikachu & Eevee between November 2018 and February 2020. It arrives in a Cherish Ball with the original Trainer “ポケセン” and Trainer ID 181116, the exact identifiers recorded in the live distribution.
What makes this version worth collecting: It arrives holding a Poké Ball — bonus items like this were part of the original handout and are preserved here. The preset moves (Pound, Celebrate) match the original distribution exactly.
IVs are generated per-trade using the event's original randomisation rules, so each one you receive is a fresh roll. Ability is set to Any12, matching the event-programmed slot.
Every event Pokémon on GenPKM is built through the same PKHeX legality pipeline Pokémon HOME uses to validate deposits, so this Chansey passes HOME, transfers cleanly across the games its species is available in, and behaves identically to a Pokémon you'd obtain yourself. To add it to your save, open the Mystery Gift trade hub, pick the Let's Go Pikachu & Eevee list, and hit trade — the bot runs a Link Trade with you in under a minute once you're queued. If you're new to genning and want the honest answer on ban risk first, read Is Pokémon Genning Safe? before you trade.
Yes. Every event recreation on GenPKM is validated against PKHeX — the same legality rules Pokémon HOME uses on deposit. This Chansey from the Happy Birthday! event passes HOME without any flags and moves freely between compatible games.
When was the Happy Birthday! event originally distributed?
The Happy Birthday! distribution for Pokémon Let's Go Pikachu & Eevee ran from November 16, 2018 to February 29, 2020. If you missed the live window, GenPKM rebuilds the exact distribution data so the Pokémon is still available to add to your collection.
How do I receive this Pokémon on my game?
Sign in on GenPKM, open the Mystery Gift trade hub, pick the Let's Go Pikachu & Eevee event list, and select this event. Our trade bot starts a Link Trade with you and sends the Pokémon directly — it takes under a minute once you're at the front of the queue.
Can I use this event Pokémon in online battles?
Ranked Battle Stadium, Link Battles, Surprise Trade, and Pokémon HOME GTS all accept this Pokémon because its data passes every server-side check. Note that official VGC tournaments separately disallow any Pokémon not personally obtained in the tournament's legal game — that's a tournament rule and applies regardless of how the Pokémon was acquired.
