Sidenote: It is pronounced Gil-ur.
When you go to the Australian Trinkets shop and buy the egg of a Ngilr you are in for a whole a lot of trouble. As soon as they hatch, they will already start to cause havoc, this will not stop until a few minutes have passed, if you do not want this to happen take the egg some safe when it starts to pulse. They start off small but can grow to twice their original size in about a week! They only eat meat so do not try to feed it anything else, it could end catastrophically it prefers steak and the native to Australia Cannonball Spider, named because its massive abdomen. When they grows up they like to be in the wild, so you have to be ready to let them free.
