Grahm's Meat-Cook

Event: Grahm's Meat-Cook is a seasonal public event It is part of the Meat Week community event.

Detailed walkthrough
When the Vault Dwellers arrive at Grahm's cookout spot, he will ask for their help in running the festivities. It may be found northwest of the moonshiner's shack, and south of Vault 76. To properly celebrate Meat Week, the players must perform a number of tasks in order to maintain a success meter displayed in the top right corner of the UI. The more filled the meter, the better the rewards given at the end of the event. Chally the moo-moo is not for eating.

To contribute to the progress bar, the player can perform several specific tasks in and around the cookout grounds:
 * Tasks
 * Continuously turning one of the three cooking spits located on the north end of the grounds, or playing one of the three drums located on a small raised stage on the southern end.
 * Although not immediately reflected by the UI, they contribute toward the progress bar during the "wait for the cookout to begin" stage.
 * Collecting critter chunks by killing and looting the various critters, such as chickens, rabbits, squirrels and opossums, around the grounds, then depositing the chunks into the "snack cart" (a shopping cart occupied by a carcass of an opossum) on the eastern side of the grounds.
 * Collecting greens from verdant green plants located in the foliage surrounding the grounds, then depositing them into the cooler on the eastern side of the grounds, adjacent to the snack cart.
 * Dispensing five wood scraps onto the pile of kindling at the center of the campsite. This can be repeated after a short delay from the last time it was activated.
 * Donate Chally's feed to Chally's feed pile
 * The recipe may only be purchased from Grahm during Meat Week (he still acts as a vendor), however the item is not instanced per player - meaning another player can beat the rest to it.
 * It may be crafted on the spot at the cooking station in the center of the campsite.
 * Cleaning up rotten leftovers and "stinky piles" around the grounds, represented by small greyish piles of brahmin skulls or dung piles respectively. Sometimes, Grahm will comment when Chally leaves a "stinky pile" so it can be cleaned up quickly.
 * Extinguishing the sporadic brush fires near Grahm's grills, signified by blackened patches of grass on fire.
 * Unless collected, the rotten leftovers, stinky piles and brush fires will deplete the progress bar.

If the player has recently completed the Primal Cuts event, they can deposit their prime meat in the large cooking cauldron, the adjacent open grills or the spit-roasting yao guai at the center of the Meat-Cook area. Prime meat may only be donated in stacks of five, and only three times per Meat Cook.
 * Prime meat

In addition to filling the progress bar, each stack of meat will be exchanged for five Legendary scrip, for a total of 15. Additionally, each stack of prime meat donated will buff the player with an increasing degree of meat sweats, the effects of which are as follows:

Once the timer runs out, or if the meter is completely maxed, the event will conclude. The event rewards are given depending on how high the meter is at the time of completion. The better the meter was, the better the rewards and Grahm's thoughts on it. Past the first objective, the event is considered "bad performance." Past the second, the event is considered "good performance." At the meter's maximum, the event is considered "best performance." If the meter is below the first objective upon the timer expiring, the event fails and no rewards are distributed.
 * Completion

Rewards
