The reward for vaporising a shark: a kit for making sushi, handed over with no further explanation.
The prize attached to the Sushi Smoothie achievement, granted when Carl obliterates the dead Concierge Shark with Daughter's Kiss and fills a Larracos alley with red mist.
It is the crawl's usual joke-gift logic - a themed consumable-crafting item awarded for an act of gross violence against a fish - and joins the growing pile of odd equipment Carl accumulates and occasionally finds a use for. Nothing about its stats or contents is given.
Not described; a kit for making sushi.
Joke loot from the chapter's achievement, and a piece of Carl's inventory.
