A new Marcel the Shell video has appeared, just in time to promote the release of Jenny Slate and Dean Fleischer-Camp's new Marcel book, The Most Surprised I've Ever Been. This kind of marketing synergy works, though it would work better if they had a video every week instead of every 18 months. No pressure.
Also, this Marcel video turns it up a notch, language-wise: does anyone have a favorite kid-size explanation for what "BS" stands for?
