Netherbug

The Netherbug would be unlocked by throwing an Ender Dragon egg into the Void. The nether bug portal(which is a portal to the normal world) can be unlocked in two ways: 1. Defeating the Netherbug by defeating the TNT spiders crawling around. 2. Taming the Netherbug  by feeding it 1 piece of spider string. When you go through the portal the first time, if you defeated the Netherbug, you will get a chat message saying: “uh oh! It turns out you only stunned the Netherbug!” Then you will be pulled back through the portal. Good news: your character escapes! Bad news: the Netherbug is pulled through the portal into the normal world with your character. So you fight it again. If you tamed it, it will follow you anywhere including through the portal.
