The Disney Afternoon Collection

This achievement requires you to play the original 1989 Duck Tails in "Time Attack" mode, from start to finish, in under two hours. Finish in this game means beating the five bosses of each world, returning to Transylvania for the final boss, and then completing the final race to the treasure. Unless you go out of your way to fully explore every level, it should take you about 15 minutes, give or take, to complete a full run.

This cannot be done in the normal game mode, nor will you earn "The Right Duck" while going for this achievement.

Some quick notes and tips:
A) You have limited lives; losing all of them will take you back to the game's start screen with your current time. Best to quit and restart Time Attack.
B) You have no rewind functionality. Despite this, you cannot earn "Be Kind, Don't Rewind" in this mode.
C) If you are new to this game, you should play through the regular game mode to get a feel for how the game plays.
D) You can select "EASY" on the start screen to make things much easier. Your health is effectively doubled, allowing you to keep more of your life and making the boss stages easier.
E) Do Boss Rush to get a feel for each boss, particularly Dracula and Magica De Spell. Remember, limited lives.
F) You can "Watch" some of the other times to see how other players get through the levels. Note that they might do some weird, even glitchy things with the bosses. It is highly recommended you do not attempt this, and play it safe. Remember, limited lives.

Lastly, check the guides for "The Right Duck" (Complete the game) for some notes on how to beat each level,
