Linux and GNU are the penguin and the bull. The creature with the K is... Sparky, KDE Plasma's mascot I think. I'm guessing the other 4 that look the same are similar in purpose.
if you can't name any of the mascots the soyjak ignores then this meme is about you, educate yourself about tech or shut the f**k up with the clippy bullshit
Correcting myself here (Kiki: Squirrel furry, Kate: Dragon, Konqi: Dragon, Other dragons: Other dragons), Kandall (Wizard), Xenn (MtF Transgender Fox who was originally meant to replace tux)
