Crab Kong does not have as catchy of a name as the crab it replaced, Crabzilla, but it appears to be bigger, weighing in at 15kg.
Disappointingly, the article press release doesn’t tell us what species of giant icky monster this, but the Japanese variety can weigh upward of 19kg, which would be truly worth of a kaiju-riffic name like Crabzilla or Crab Kong. I think it is also why Gamera isn’t as popular a kaiju as Godzilla. You can’t add -amera to something and conjure up something giant and menacing.
Regardless, it is reason enough not to go into the water.
