Partrick is a character appearing in Super Mario Maker 2. He is a living Brick Block who appears in the Course Maker as well as in the game's Story Mode. His name is based on the name "Patrick" and the word "part", due to him being the symbol for course parts in Course Maker.
In Course Maker, he is seen in the top left corner beside Soundfrog. When the player touches the icon, sounds can be used. When the icon is touched again, course parts can be used.
In Story Mode, if the player completes Mr. Eraser's first job, he erases blocks covering a nearby red Warp Pipe. After the pipe is opened, Mario can enter it to find three Brick Blocks. Once one of them is hit, Partrick reveals himself and offers the player three different jobs: House of ! Blocks, Darkness Ahead, Darkness Below, and High atop Thwomp Tower. Once the first course is completed, Partrick adds a ? Block to the second floor of Peach's Castle. After the second course is completed, Partrick causes a Hidden Block to appear over a nearby red flower. The block contains a vine which leads to Soundfrog. Completing Partrick's third and final course unlocks the Partrick Shirt.
