For one, if there would be a White Gobul, then that would be pretty redundant since there's already another White Subspecies on Deserted Island. Also, Plesioth back in the older MH, and in MHFU, it can cause sleep, that's why Sandman Spike, Plesioth Crystasword, is made of Plesioth Materials and causes Sleep.
