"Fat Marmot Week is an opportunity to get folks excited about yellow-bellied marmots, one of our favorite alpine residents, and to share the science behind their weight gain," scientists wrote.

Marmots – like bears – hibernate all winter long to sustain and survive their winter slumber, so they need a respectable layer of fat. This means these round rodents in the ground squirrel family need to pack on pounds!

From August 24-29, the public can cast a vote for whichever marmot they think made the best gains in Colorado's Crested Butte area in a bracket-style battle.

Fat Marmot Week is basically the Rocky Mountain response to Alaska's humongousily popular Fat Bear Week.

It promises to be a fun marmot awareness campaign – the researchers even announced the coming contest on their Instagram with a banger of a teaser.

Plus, the RMBL scientists already won over the internet with their creative response to the withdrawal of federal research funding. They created an OnlyFans page for their marmots, and it's gotten a whole lot of attention!

Don't worry, the OnlyMarms isn't anything scandalous – it just shows videos and pics of cute marmots.
