As of my last knowledge update in October 2021, the "Skibidi Toilet" phenomenon and its association with "ASTRO" had not been documented. However, there has been a trend on platforms like TikTok and YouTube involving quirky and humorous animations called "Skibidi Toilets," which featured anthropomorphic toilets dancing and engaging in comedic antics.
This trend often includes catchy music and has gained popularity for its absurdity and humor. If the "ASTRO" aspect refers to a creator or a specific iteration of this trend that emerged after my last update, I wouldn't have information on that.
For the most accurate and current information, I recommend checking the latest posts or videos from relevant creators on social media platforms.
