Found what? I'm having the same problem, gave him 50 cube meats two times already and he does not go away, his hunger can't be stopped
Also there appears to be another glitch with the ground items in the driver savanna area, the game showed the graphic of me getting the item that looks like a pink carrot quite a bunch, but every time I didn't actually get it, but got the orange carrot instead. Not sure if it's a case of the wrong graphic being displayed and I just wasn't lucky enough to actually get a single pink carrot, or if it's a more serious glitch and I can't even get the item (I'm playing on Android, btw)
