(05/02/2020) I attempted to add the ears during this lunch break. The mesh density varies a lot and gives weird results when sculpting. I think re-making them from scratch and making sure the density stays constant is better than trying to fix this at this point.
(05/02/2020) Found out what the problem was! The scale of the base cylinder mesh was not applied and interfered with the sculpting tools, all is better now! 😃
