What happened

On June 1, 2026, Baskin-Robbins Japan — branded locally as 31 Ice Cream — opened a nationwide collaboration with Dragon Quest, the long-running Japanese role-playing game franchise, to celebrate the series' 40th anniversary. The campaign runs through June 30, 2026, while supplies last. The headline item is the Popping Shower Slime: the chain's popular mint-and-candy "Popping Shower" flavor reimagined as Dragon Quest's iconic blue Slime monster.

It is not a flavor but a keychain bundled with the "Dragon Quest 40th Set." A new limited flavor, Golden Pineapple Lemonade (Japanese name "Kaishin no Ichigeki," meaning "critical hit"), pairs lemonade and pineapple sorbet with the chain's first-ever popping candy and sells for 420 yen.

Why it is trending now

The spike came from an official giveaway on X (formerly Twitter). Until 11:59 p.m. JST (Japan Standard Time) on June 1, fans who followed the brand and replied with the campaign hashtag could enter to win one of 31 prizes of a 500-yen eGift. Dragon Quest hit its 40th anniversary on May 27, 2026, so the launch landed right as fans were already in a celebratory mood, drawing both gamers and ice cream fans.

How fans reacted

Reaction on X skewed heavily positive. Many users called it a dream pairing of two things they love, gushing over the Slime keychain's cute design and posting plans to visit stores the same day. Others said they wanted to taste the fizzy popping-candy flavor, while some praised Dragon Quest's original Slime design and asked for the crossover to appear in the spin-off monster games.

What to watch next:

With the collaboration running only through June 30 and items available while supplies last, watch for sell-outs of the 40th Set and the keychain, plus whether Baskin-Robbins Japan or Square Enix expands the tie-in with restocks or additional merchandise during the anniversary year.
