i think you're referring to that frog field boss. when you beat certain field bosses you get to 'transform' into them and take on their abilities. on ps5 that is done by hitting R2 and L2 at the same time - which it sounds like you did. unless i missed something.I need to get back on the game... I only played the first chapter up to the point I got turned into a beetle... That big head green creature is the last thing I remember... Undisputed has taken over my gaming experience, I need to step back because it's forcing me to neglect my other games
