Yikk is a character that appears in Mario & Luigi: Bowser's Inside Story and its 3DS remake, Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. When Bowser enters the Tower of Yikk, he finds and reads through a book he finds on a desk. Bowser's way out is then blocked off, and Yikk appears from the book as a ghostly apparition. Yikk claims he invented the Tower of Yikk and the Boo-ray Machine. He created the Boo-ray Machine to study Boos and other spiritual beings. After Yikk explains his machine and how to use it, he shuts the book and goes back into slumber.
Yikk is similar to Professor E. Gadd, as both characters study ghosts, and both of their names are puns on exclamations ("ick" or "yeek" for the former, "egad" for the latter).
