Because like, look, the manager, his wife and him are looking at this like, 'What flavor should we do? What makes business sense?' Because my fans have been asking for my flavor to return. Cotton Candy forever."He also mentioned that he would have been willing to give them his "blessings" if Tyler had asked for his permission first:"Now, if Ninja would've came to me and said, 'Keem, can I bring Cotton Candy back?', I'd be like, 'Yeah! You have my blessing. You're my homie. Go ahead. Rock it, rock it!'"Keem then added:"Like, that he would have the full blessings, but that's not what happened, okay? Ninja didn't say s**t to me. His wife contacts me and says, 'Hey, we just want to let you know that we're launching a Cotton Candy can.' All right? She didn't f***ing ask for my blessings. She didn't ask for s**t!"The YouTuber also claimed that he had reached out to the streamer on multiple occasions but failed to get in touch with him. He also called Tyler a "blue-haired freak."Fans react to the content creators' beefMultiple conversation threads on Twitter had fans discussing the beef.
