Hello, I'm SummerPhDv2.0. I noticed that you added or changed content in an article, Happy Tree Friends, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Sum mer PhD v2.0 17:08, 2 May 2020 (UTC)
