A new Lumon perk for employees to enjoy!
A new perk for innies offered as part of the Severance Reforms, bobbing for pineappples appears to be a variant on the old-fashioned party game bobbing for apples, wherein a tub of water is topped with floating apples. Players kneel by the tub with their hands behind their back and using only their teeth, try and grab an apple. Pineapples are famously much larger than apples, as well as have thick, spiky rinds. This would make this perk something more in keeping with the old Break Room's usage.
This perk is only visually referenced in the Thank Kier for the Macrodat Uprising video, thankfully.
