The Mysterious Pyramid

The Mysterious Pyramid is a comic story written by Vic Lockman, penciled by Tony Strobl and inked by Steve Steere. It features Donald Duck, Professor Pintail, Gladstone Gander and Daisy Duck.
==Plot==
Donald Duck is caught sliding down the ballister of the Duckburg City Museum's stairs for fun, something he has liked to do ever since he was a child, by the director of the Museum himself, Professor Pintail. However, rather than scold him, Pintail compliments his skills and invites him to go on an archeological trip with him to investigate the only Incan pyramid with a ballister, as he wants to test whether that ballister was, in fact, intended for sliding, or not. However, robbers who believe they will find priceless treasures in the pyramid follow them.
===Continuity===
* Professor Pintail reappeared in Beyond The Moon (1963) and Injun Expert (1964), now depicted as an astronomer. No explanation is given for this late career change.
