Marcel the Shell with Shoes On is one of the cutest, most ridiculous videos to this day.
So it's no wonder that Jenny Slate continually does the voice of the character whenever and wherever she can.

She did a cover in the Marcel voice. But not just any cover, no, no.
Jenny as Marcel covered the iconic song Landslide by Stevie Nicks and it's pretty freakin' impressive!
