Jack Lumbear is a giant bear who appears as the tenth boss of Goop's World 2, appearing in the level Jack Lumbear's Mill. This level is the last level in the Pine Heights area. He is an enormous grizzly bear dressed in lumberjack clothing and wielding a chainsaw. He speaks in a gruff Canadian accent and has a prejudice against Gooptars for some undisclosed reason, referring to them as "varmints". After his fight with Goop, he plummets off a cliff and into a raging river, but whether or not he survives is unknown.
