Find the 20-Million-Won Mattress Pop-up Seongsu

A birthday-party-themed flagship pop-up at Trend Pot by Olive Young N Seongsu, celebrating Pokémon's 30th anniversary as part of Pokémon Mega Festa 2026. The space is filled with cake, ribbon and balloon photo zones, a coloring corner, and exclusive 'Birthday Party Edition' merchandise — including the highly limited 'Pikapika! Pikachu' commemorative plush.

Part of Pokémon Mega Festa 2026, Metamon Playground transforms a Seongsu side street into a purple wonderland packed with giant Ditto sculptures, photo zones and a record-shop-themed indoor store. Entry is free via an on-site QR queue, and the venue includes limited 30th-anniversary goods, a Pokémon TCG area on the second floor, and a takeaway Ditto Cafe.

Ditto (Metamon) takes over a playground in Seongsu for the official Pokemon-themed pop-up. Enter a pink, squishy world where Ditto has mysteriously copied everything from slides to stuffed toys, and shop limited Ditto-only merchandise. Part of Pokemon Megafesta 2026, the event runs daily 10am to 9pm from May 1 through June 21.

Pokemon Secret Forest is the third event in Pokemon Megafesta 2026, hosted at Seoul Forest.

Tied to the 2026 Seoul International Garden Expo, it's a magical outdoor experience open daily from May 1 through June 21.
