Uncle Niko's Olive De-Pitter

Uncle Nico's Olive De-Pitter is a present that Arthur got his dad in Arthur's Perfect Christmas. It was purchased at Kitchen Crafts (a store in Mill Creek Mall). However, Arthur was hesitant about buying it at first, until a worker said that he would give him a jar of free olives.

In the beginning of "Dear Adil", David Read was looking for his Olive De-Pitter with the help of D.W. and Arthur. Arthur had found his dad's old pen-pal letters and as they were talking about them, D.W. found the Olive De-Pitter. Although, in the episode, it is red instead of yellow.
