Jenny Slate is so into her Marcel the Shell character that she's started slipping into his tiny little voice during her everyday life, and occasionally sings cover songs as Marcel just for shiggles. On Conan last night, she busted out a particularly good one: Fleetwood Mac's "Landslide."

That tiny mollusk has a surprisingly huge voice when he really goes for it.

Slate's husband, Dean Fleischer-Camp, has apparently nixed the Marcel voice during sexprobably good because that's creepy—but he's totally into Marcel's Stevie Nicks impression, which is so good (or so insane?) that it made him cry.
