Digger Doug

Digger Doug is the parody of the arcade cabinet Dig Dug itself. It appears for the Castle Arcade merchandise release for the 2nd season of Yoshi's World: Weirder Eggs, for it appears in the series when Catty plays it and beats the high score Dave the Donut Dragon had put in place, dropping his to 2nd on the leaderboards, under Catty's nickname "MADCATTY".

Gameplay
Very simple, indeed. Use the joystick to move/dig, and when within range, use the air pump to inflate the Ballookas and Flydras. Another way to kill them is let them off screen, and they'll die then.

The Character
Digger Doug, as a character, looks almost like Sir Kibble from the Kirby series, but with white armor, a blue face, a visible mouth and eyes, red feet, white gloves, and a green air pump/red shovel. His job is to inflate 'em (by 'em I mean the enemies) up to beat the levels.
