This variation is for both NTSC and PAL as there is no difference between the two on the Intellivision Video Game Console. Play One-Player only. It is the Player’s choice to use the left-side or the right-side Frog. The other Frog must be controlled by the computer. It is the player’s choice to play either the “Day” or “Night” Session. It is also the player's choice to use “Manual” or “Automatic” controls for your Frog’s arc and for your frog’s tongue action.
