Press the flag, and, after the logo goes away and a start button appears, click that button. Then, a question will appear. Read the question, and click on the choice that best describes your answer to the question. At the end, based on your choices, the pet that you should get will be chosen, and the background will switch to the background that goes with your pet. You can also view the list, which will tell you who got what on this quiz (I'm a cat). Update: We have a cloud list added (a few users somehow managed to create a Cloud List)
Thank you to @lirex for the cloud list! I thought it was impossible... Thank you to @deck26 , @Nether_before , @ChocolatePi and @sigton for participating in my help post to help me to decide a 4th animal to include. Thank you to @ItchyCatIIII for the logo. Thank you to @MyRedNeptune for the music, which can be found here: https://scratch.mit.edu/projects/451954/ (the only difference is that I added a forever block around the script that was broadcasting each part of the music, so that the music would constantly play.
