A sequel of sorts to the incredibly unique You Have To Burn The Rope, You Have To Fertilize The Egg is much more... interesting. Taking place inside a vagina, you play a top hat wearing sperm on his way to fertilize an egg and "make the princess". It's all rather silly, especially since the song, instead of urging you on like the You Have To Burn The Rope song, describes your exact situation. Thankfully, nothing is actually explicit, instead being rendered in cute black-and-white cartoony graphics. It's there for a giggle, and it definitely elicits one, especially since there's nothing else to the game.
