One main use of the Wind Ring is helping Klonoa with doing higher jumps that he normally is not able to do, throught somehow the character alone managed to jump and reach where Joka or Joker if this is his actual name now was standing in the end of V1-2.
That's not the last time Klonoa does that at his own, other time he does a not so high but longer jump when he sees Karal again at some point in the game.
Not wanting the Wind Ring to be less useful in a game made with it in mind, just pointing out this (maybe intentional) inconsistency with the character in some cutscenes.
