Evolution of Sonica and Tailsko


 * While this isn’t described as a Tailsko, it’s the first appearance of a female Tails on Tails and Sonic Pals. The first ever appearance of a girl Tails was in the 39th video named “SONIC LOVES ME? | Tails Plays Sonic Mania (Female Tails Mod)” published on Oct 5, 2019 This girl Tails resembles Tailsko but has a blue skirt and a pink shirt. As made aware by Tails at one point, female Tails has breasts despite being 8.
 * Sonica’s first appearance was on a thumbnail for another video named “SONIC IS A GIRL!? | Tails and Amy Play Sonic World MODS” She obviously resembles Sonic but has eyelashes, and a red bikini. Her designs in her first 3 actual appearances are modeled like that.
 * Tailsko gets mentioned by Sonica in “Tails and Sonica Play Sonic World (Female Sonic Mod)” and by Sonic, Tails and Sonica in “Sonic Meets Sonica | Tails Plays Sonic World”
 * In “Tails and Sonica Play Sonic The Hedgehog 1 (Female Sonic Mod)”, Sonica appears in 2D for the very first time. Here, her bikini is purple-ish and has a picture of a ring on it.
 * Tailsko makes her first appearance in “Tails Meets Tailsko | Tails Plays Sonic World (FT Sonica)”. Her design doesn’t resemble Tails that much, has hair and wears a striped orange dress. This is the only time that design appeared.
 * Tailsko and Sonica did not appear in 20 videos until “Tails & Tailsko Play Would You Rather? (Female Tails)” Here, her design resembles Tails more, has a red shirt which has a picture of a wrench, a toolbelt, and blue pants. This was published in “January 22, 2020” making the first time Tailsko appeared in a video published on 2020. She also has more emotion vectors.
 * Sonica makes a cameo during the end of “Sonic Meets Tailsko | Tails Plays Sonic World (FT Sonica)” which is the last appearance of her in her previous 2D form. “Sonica and Tailsko Play Sonic World (FT Tails)” is the first appearance in her current 2D form. Here, she wears a red skirt which has 4 rings. Her clothes also turn back to red as she is drawn in a design similar to Tails, Sonic and the other characters on the channel.
 * The last appearance of Sonica and Tailsko to date was in “Sonic and Sonica Play Sonic World (FT Tails and Tailsko) - Female Sonic !”
 * It’s also worth noting that Tailsko never appeared in a 3D design on the channel.
