Leap into Learning was the default sampler book for LeapPads from September 1999 to September 28, 2001. This interactive book does not require a cartridge and is the very first book for the LeapPad Learning System on the launch day.
The British version cuts off the United States of America page, shortening it to 30 pages (instead of 32 in the original USA version). Also, the original USA voice cast is replaced with the British voice actors and actresses (including David Bamber (Storyteller), Susan Sheridan (Leap) and Emma Tate (Lily and Tad) for the pages with Leap, Lily, and Tad).
The LeapPad Pro version does this too, cutting it much shorter to 10 pages (excluding Lil's Loose Tooth, Excerpts from Richard Scarry's Best Word Book Ever, and Disney's A Sweet Good Morning). A different title for this has the same version and more interactive books with cartridges.
The voice actors are replaced with the British voice actors/actresses for those who have a British-English accent; these include David Bamber (Storyteller), Susan Sheridan (Leap) and Emma Tate (Lily and Tad) for the pages with Leap, Lily, and Tad.
This is the first time that Leap, Lily, Tad, or the narrator breaks the fourth wall.
