Chrome Deathbot
From MHWiki
The Chrome Deathbot, also known as the ChromeBot, was a Limited-Edition trap which, as of October 14, was only available during the Hunter's Reward Weekend of August 16-18, 2008. The availability of the trap coincided with the only appearance of Ronza's Traveling Shoppe, the Chromebot being the only item that Ronza was selling.
The ChromeBot is currently the second most powerful trap available to hunters. Its appearance is similar to the Mouse DeathBot but is entirely gold and silver plated, with a large necklace hanging from its head. The plate upon which the cheese is baited is also covered in gold.
