[3] Most of the animated film's original voices were not used in any of the in-game dialogue, except for the cutscenes, while Frank Welker and David Cross reprise their roles as Curious George and Junior respectively.

[6] The levels also feature a series of highlighted objects, which award the player "curious points" for interacting with them.

[5] These points can then be used to unlock bonus items, which include hats that George can wear in-game, and the ability to replay minigames and cutscenes.

[7] The game features four minigames, three of which are fairly similar, requiring the player to press a button at the correct time.

[3][7] The game begins with Ted discovering an ancient idol in an African jungle, only to find it is three inches tall.

Upon his arrival, his scent attracts the attention of Ivan, the building's doorman, who enforces a "no pets" policy.

Junior (voiced by David Cross), the son of the museum's owner, becomes suspicious after Ted repeatedly mentions a monkey, and sets out to find George.

Left with nowhere to sleep, the duo take refuge in a park, where they find solace in the fireflies, which George collects.

[26][27][28][29][30] The console version was praised for its cel-shaded graphics, which reviewers felt were able to capture the cartoon style of the film.

[3] A review for Gamespot described the level design as "extremely linear" and without "measure of exploration",[5] and the interactive objects were described by Eurogamer as "a nice idea" but "pointless" due to their repetitiveness.

[3] Eurogamer characterized the final balloon minigame as "a staggering EIGHTEEN rounds of lethargic bemani action".
