The Leapster TV variant can be seen here.

Logo:
 * Original Variant: On a white background, we see a set of blue abstract squares forming and eventually filling the screen. Then we see a split second of the text "LEAPSTER" (in blue). We then cut back to the white background and see the text zoom in towards the screen. As of 2006, a copyright notice appears.
 * Leapster TV Variant: We see multiple letters flying around the screen which form "LEAPSTER". Then, a blue rectangle enters the screen. Inside the rectangle is blue "static", resembling TV static. A blue cord slides up and pops itself into the rectangle, causing the static to transform into the word "TV". The rectangle then implodes and the same word "pops" in.

FX/SFX:
 * Original Variant: The squares forming, the text zooming in.
 * Leapster TV Variant: The letters flying around, the static, the cord, the "pop".

Music/Sounds:
 * Original Variant: A rising synth note, then a warbling melody. This was extended and rearranged in 2005.
 * Leapster TV Variant: A happy-mood tune, and a pop when "TV" appears.

Availability: The original variant can be found on the original Leapster consoles when you turn on the console, also seen when you turn on a Leapster TV with a Cars cartridge inserted to the slot, The Leapster TV variant was seen when you turn on a Leapster TV console.

2nd Logo (2008-2019)
Can be seen here.

Logo: On a white background, we see a green "2" bounce to the middle right from the top right of the screen. A blue cord plugs itself in the open space on the "2". We zoom out. As that happens the cord fades out. "Leapster", in blue, fades in.

FX/SFX: The "2" bouncing, the cord plugging itself in, the zooming and fading.

Music/Sounds: A 3-note high-pitched theme.

Availability: Seen on original and special edition Leapster2 consoles.
