Expresso

Expresso the Ostrich is a large ostrich wearing sneakers and friend of the Kongs.

Donkey Kong Country
Expresso's first appeared in the game Donkey Kong Country as one of the game's four rideable Animal Buddies. Expresso can run at fast speeds and glide through the air by flapping his wings rapidly. Interestingly, Expresso has no offensive capabilities at all, meaning that he has no way to defend himself against threats; though some small enemies may pass under Expresso's legs, leaving Expresso unharmed.

Levels that Expresso appeared in:
 * Levels
 * Temple Tempest
 * Orang-utan Gang
 * Ice Age Alley
 * Misty Mine

Donkey Kong Land
Expresso reappears in Donkey Kong Country's semi-sequel Donkey Kong Land as one of the games two Animal Buddies (the other buddy being Rambi). In this game Expresso's abilities remain relatively the same as before, except he can now defeat enemies, even Zingers.

Levels that Expresso appeared in:
 * Levels
 * Deck Trek
 * Landslide Leap
 * Mountain Mayhem
 * Collapsing Clouds

Club Nintendo
In the Club Nintendo comic "Donkey Kong in: Banana Day 24", Diddy and Dixie Kong are briefly seen riding Expresso to an airport.

Other
Aside from Donkey Kong Country's various remakes Expresso has yet to reappear, though an identical ostrich, also known as Expresso (or Expresso II to some) appears in the Game Boy Advance version of Donkey Kong Country 2: Diddy's Kong Quest.

Though Expresso, along with several other ostriches, appeared in the trailer for the apparently canceled game Donkey Kong Racing, it is unknown if Expresso was going to be a ridable character or not.

Trivia

 * An ostrich that resembles Expresso can be found in Jinxy's Dunes in the game Banjo-Pilot.
 * Cranky Kong expressed desire in the Donkey Kong 64 players manual that poor Winky and Expresso should appear in the game, not that swordfish or that "bone-brained rhino that always seems to get in the games".
 * Expresso's shoes bear a resemblance to the Running Shoes in Banjo-Kazooie.
