Tsvetnysh🌈

She's the first female character in the Bubu series. Khvostik's personality is somewhat similar to Igrulya's: kind but fair. Khvostik dislikes arguments and wants Bubu and Vasyan to stop arguing as quickly as possible. If anything happens, she'll always stand up for the characters and help them if they overdo it, and she might even punish them.

Bubu is often cheeky and loves to eat. He's often stern, although in some situations his sternness is more of a defensive reaction than a character trait. However, he can also be kinder and gentler at times. He may have a love interest in Svetik, as hinted at in older episodes on the Khvostik TV channel, where Bubu would show off in front of the kitty, or even wash himself before meeting her. Bubu loves to eat, sleep, and play, and never misses an opportunity to tease his best friend, Vasyan. Despite his sternness, Bubu is forgiving and reconcilable. He really dislikes bathing and eating peppers. Bubu loves to show off, which sometimes only makes things worse. Bubu has a best friend, Vasyan, whom he loves to tease and joke around with, but Vasyan can also do the same. Bubu loves to joke around with others, but when jokes are made at his expense, he can become offended or angry. Sometimes Bubu and Vasyan have arguments that can take them a long time to resolve, but more often than not, they're unable to resolve them on their own. Despite some moments, Bubu can be quite clever and cunning, such as when he turned Vasyan's revenge prank in episode 99 on the "Igruli TV" channel against him, albeit imperfectly, or in episode 109 on the same channel, where he helped his friend Vasyan win the "Football" minigame. The character can sometimes be lazy. Bubu can also be quite cruel at times.

Tsvetnysh tries to achieve his goals, even if it means stealing colors from another planet. What makes him so determined is that Tsvetnysh's goal is to steal colors for a light show. He built a machine that can make entire movies out of color, but for it to work, he needs a lot of colors. First, Tsvetnysh collected all the colors from his home planet, but that wasn't enough, so he pumped all the color out of it, but even that wasn't enough. Because of this, he flew around planets to collect as many colors as possible and then show everyone in the universe a light show. The gray cat thought they would be happy about this, although they weren't. But at the end of episode 37, the only episode where he appeared, Khvostik and Bubu surrounded Tsvetnysh, and he returned everything to its place. He left and was never seen again. Of all the characters, he has the fewest appearances, namely one, if you don’t count “The Stern Cat Bubu and the Doggie Dudu School”, where the penguin Elsa also has one.
It is unknown why the inhabitants of Tsvetnysh's home planet did not confront Tsvetnysh; perhaps they were afraid.
Tsvetnysh isn't really a villain or antagonist, but rather an antihero. He's neither purely good nor evil; he simply had a goal to pursue. He had to play games with the kittens Bubu and Khvostik because he wanted to get colors, not because he wanted to kill them. Although at the end of episode 37, he showed himself to be selfish, so it's hard to call him a villain at the end of the episode, let alone at the beginning. The word "color" in English is "color," and it was decided to leave "nysh" unchanged and use the transliteration "nysh," resulting in "Colornysh."
