Sea lions are afraid of similar memes

Sea lions are no longer afraid. It refers to a meme of Lin Yanjun, a contestant in the talent show "Idol Producer". He especially likes to tell cold jokes on the show, and this joke is one of them. The main content is this, do you know which animal is the timidest? I don’t know, what. Sea lions, because sea lions are (still) scared and won't be with you when they wake up... (a line from the song "Still Will").
