SML Movie: Jeffys Mistake a deleted scene

Well I love Supermariologan. His channel is Awesome. I saw a video called Jeffy's Mistake. Logan posted on his SuperLuigiLogan account called Jeffy's Mistake Deleted scene. That's all it said. I watch and scenes started with Jeffy wearing his Pooperman shirt but everything was black and white. The next scene started with Mario asking Black Yoshi to babysit Jeffy while he and Rosalina were gone. Black Yoshi said Okay. The babysitting Started with Black Yoshi pranking Jeffy by making him play Five Nights at Freddy's. Jeffy played until Bonnie Jumpscared him and Threw Black Yoshis Tablet out the window and Black Yoshi Returned and said MY TABLET WHAT DID YOU DO?!?! Black Yoshi was so mad he took jeffy and Threw him into the pool and he never returned. I was shocked and stopped watching the video.
