Template:Gaddget Eye Exam is a type of Gaddget, which, like all others, is invented by Professor E. Gadd. It appears in Mario Party Advance.
Summary
This Gaddget can be obtained via the player completing the quest Weeping Thwomp. Despite the name, this Gaddget is more of a fiddling tool.
Once played, the game starts with a right-side up C zoomed in by 20/200, also being able to alter itself to 20/100, 20/60, 20/50, 20/40, 20/30, 20/28, 20/25, 20/22, 20/20 in terms of size, all being ten optional ones total. Once fully zoomed in, the C-shaped silhouette can be changed to Yoshi first, then Princess Peach, then Luigi and then Mario. The down button can be used to revert the images back. Only the c-shaped silhouette can be altered. Pressing the A button eight times allows the C to be reversed one whole time.
