A video showing a massive spider crab, bought from a fish market and brought home to a bathroom for observation, recently went absolutely viral on Twitter (now X). The star of the video is Rikuto (@naze6622), a content creator known for cooking exotic ingredients. He snagged the colossal crab from Yoshiike, a seafood specialty store in Tokyo's Okachimachi, and decided to give it a temporary home in his bathroom. The internet, naturally, went wild with surprise and discussion. 
The video kicks off with Rikuto's camera focused on the crab, which starts scuttling across the bathroom floor with a distinct "clack-clack-clack." Viewers immediately dubbed the scene "terrifying."
"Wait, the spider crab from Yoshiike is still alive?! That's insane!" Rikuto exclaims, his voice laced with surprise, as he zooms in on the crab's face. Its mandibles and mouthparts are visibly twitching and moving with alarming vigor, making some viewers wonder if they might become its next meal.
The bizarre footage sparked a flurry of reactions, with many netizens calling the scene both frightening and utterly surreal. One user commented, "This is so weird, the bathroom just turned into an aquarium!" Another likened it to "having a Kani Doraku sign right in your own home." One particularly witty netizen even joked, "For a second, I thought this was a scene from 'Monster Hunter'!"
Rikuto, however, playfully questioned why he put the crab in his bathroom, despite it being his own purchase. In a post about buying the spider crab, he humorously wrote, "I've really gotten myself into something terrifying."
As the video blew up, Yoshiike's official account even chimed in, stating, "Well, at least it's alive!" Many users commented that they had seen the giant spider crab during the day and were stunned by its sheer size.
The spider crab's ultimate fate was revealed in a follow-up video. Rikuto humanely dispatched the crab with ice water, then showcased the dissection process, revealing succulent crab meat, the shell, and a generous amount of kani miso (crab innards). Everything but the kani miso was used to make a delicious crab hotpot, which received rave reviews.
