Jumping Frog was added in Beta 50.0. Previous Versions can be found here.
Jumping Frog is the latest Frog added to the game, with the ability to deal its ATK as DMG to an enemy monster of your choice when played, effectively working as a combination of Haste and Ranged (as counter-DMG isn't applied), while also able to ignore Taunt.
Both Final Froggit and Reaper Bird are able to buff this before this is on the board, increasing not only its stats but also its DMG output from its Magic.
