Meta’s year so far hasn’t exactly been a picnic. But that didn’t stop one nut-loving creature from seeking some joy inside one of the company’s offices this week.

A squirrel apparently got loose inside a building in Bangkok, Thailand, where some of the tech giant’s regional teams are based. The critter spent at least 20 minutes darting past staff, according to an internal memo seen by WIRED. It noted that the squirrel minorly injured a janitor before finally being caught.

The rodent’s adventure in the office—while potentially terrifying to some—brought a moment of levity to Meta staff around the world who have been dispirited by recent restructurings, mass layoffs, and the launch of an initiative to train AI using employee data without their initial consent. Meta executives have acknowledged the current morale crisis and begun trying to lift the mood internally by funding boozy social outings and promising to improve office food, according to current employees and an internal memo.

In recent years, some Meta workers have complained about losing access to healthy office snacks, like nuts, which they said had been replaced with less nutritious options such as chips. Whether the animal marauder in Bangkok found anything to its liking couldn’t be learned.

The squirrel was delivered to the office inside a package, but it ended up escaping, according to the internal memo. A janitor from a cleaning company accepted the delivery. The reasoning behind the squirrel’s delivery and where it now resides weren’t mentioned in the memo, but some people keep the animals as pets or eat their meat.

Meta declined to comment on the incident.

The injured worker, who was scratched on the finger, received first aid and was later taken to the hospital for a medical examination, according to the memo. The janitor “responsible for bringing the animal onto the premises” formally acknowledged their misconduct and committed to adhering to office regulations to ensure “such an incident does not recur,” the memo added.

New York Times journalist Mike Isaac first reported the incident in a social media post on Tuesday, without specifying the location or the janitor’s role. “Employees are predictably having a field day with it internally,” he wrote. “One person created an AI-generated video mimicking an HR training course on squirrel-related office best practices.”

Squirrels looking for a suitable home in Meta’s empire might find better luck invading Hawaii, where CEO Mark Zuckerberg’s personal cattle dine on home-brewed beer and macadamia nuts.
