Happy Little Trees! This is a Bob Ros mug that changes when filled with heated fluid. While room temperature or cold, the mug is black with a classic Bob Ross portrait and Quote, "We Don't Make Mistakes. We Have Happy Accidents." I think the chips (shown in pics/videos) only add to the sentiment! I hope this piece makes your place happy! #bobross #happylittletrees #colorchanging #mugs #homedecor #treasurehunting #nostalgia #happy #happyplace #trees #popculture #eclectic #satin #collectible #antique #coffeemug #whimsical
