Killing the egg spiders
If you're getting annoyed by those little spiders that occasionally smash out of eggs instead of nectar/spray, then you'll be glad to know that they can be killed. When they smah out, whistle on your pikmin to stop some of them running around, then throw them at them. A well placed hit on their backs will kill them instantly, occasionally dropping nectar. Take their corpses back to the onion/ship and you'll get their entry in the Piklopedia.
