it can nullify heavy attacks too (ex: warpath or a full power ghost) but you either need to be very long or just fully coiled idk
tailwhip enemies they will be wrapped in your tail during that time you need to get them right next to your head/body and idk click on them to vagi vore them, idk because sometimes it just happens when i play
edit: i think the visual changes end at like fifty or forty
you see the number would go up with every capture and you would get longer
