I see Yoda as always having had a mischievous side he had to keep in check being a proper Jedi master. He doesnāt have to be super serious all the time anymore. Being dead for 30 years is probably liberating. He could also be laughing because he knows the books arenāt even in the tree? Perhaps Frank Oz will chime in one of these days about it. Heās been fairly protective of Yoda.
And I think when the Yoda puppet is eventually seen in behind the scenes photos, it will become clear itās the lighting that makes him look odd in certain shots.
