The Legend of Zelda (video game)/YMMV


 * Demonic Spiders:
 * Blue Wizzrobes are constantly moving and teleporting around where they deem fit, and take six swings to kill with the White Sword - even the impressively-powerful Magical Sword needs three hits to dispatch one, and the only other weapon that works on them is bombs. If you're in their line of sight, they fire a beam that'll take a whole heart on contact even with the Red Ring; they also love to hang out with Bubbles that temporarily disable your sword on contact, and Like Likes that will try to eat your beam-blocking magic shield. You see a blue Wizzrobe, you do what we do. You run your ass off. Unless the next room is sealed and you're forced to fight them - and it almost always is.
 * Darknuts have been consistently a thorn in players' sides throughout the series, and they make their debut as a commonly-cited example of this. Encountering thetm in the third dungeon is one of the many signs for you to pick up the White Sword - even then, you can't attack them head on, and they walk around in erratic enough patterns to foul some attacks from the side or back. Thankfully, two hits with the White Sword is enough, and you can also hit them with bombs, the Magical Rod or unenhanced magic blasts from the Rod - they're immune to everything else.
 * And those are just the red Darknuts - the blue ones are even worse, being faster and stronger. You encounter them in the 5th labyrinth, and have to go through at least 2 rooms full of them to get the Whistle, which is required to complete the game. Odds are if this is your first playthrough, your best option is the White Sword, which requires 3 hits to drop them - the Magical Sword reduces that to 2 hits if you can find it. Their speed also makes it much harder to land attacks from the side consistently.
 * Memetic Mutation:
 * The series' distinctive Item Get jingle and pose for Link made its debut in this game. DU-NU-NU-NAAAAAAAAAAA!
 * "It's dangerous to go alone! Take this" is a quote said by the old man who gives you the Wooden Sword, and has been given a Shout-Out in many a video game since.
 * Those who played I Wanna Be the Guy may be thinking of a somewhat crass follow-up to this quote.
 * "Dodongo dislikes smoke."
 * "Grumble, grumble..."
 * "It's a secret to everybody."
