This one made me laugh pretty hard, congratulations.
Anyhow I’ll pop in here:
“Smeltal The Meltal”
Get too close to a hydrothermal vent in the multicellular stage and boil to death
“I got this!”
Kill a cell with toxins while it’s being engulfed by another cell
“Truly a plant”
Evolve a microbe with a chloroplast, a nitrogen fixing plastid and a cell wall.
“Bluegrass and fungus”
Evolve a blue eukaryotic microbe with a chitin cell wall, and a chloroplast and a nitrogen fixing plastid.
“Pac-Man cell”
Eat 10 bacteria within 10 seconds.
“Honey I’m home!” Or “Gap in the fossil record”
Return to a patch your species previously went extinct in.
