18. How many times does Birdo appear in "Super Mario Bros. 2"?
From Quiz Let's Play 01: "Super Mario Bros. 2" Part 1
Answer:
Eighteen
Birdo appears as someone you must defeat in 1-1, 1-2, 2-1, 2-2, 3-1, 3-2, 4-2, 5-1, 5-2, 5-3, 6-1, 6-2, 6-3, 7-1, and 7-2. He also appears in 4-3, but rather than defeating him you must ride his egg across an otherwise impassable waterfall. 2-2 features our first red Birdo. 5-3 and 6-3 are notable for making you fight Birdo in addition to those World's perspective bosses, as 1-3, 2-3, and 3-3 do not feature Birdo fights. 4-1 is the only level (that does not feature a World Boss) to not have Birdo. 7-2, the end level, is also unique as there are TWO red Bridos, though you only must defeat one and can completely ignore the other. 7-2 also features the only Birdo that has is holding a key rather than a Crystal Ball.
