Yay! In this new update the Pygmies(islanders) are now able to defend themselves from the T-Rex by throwing a spear at it. The T-Rex has a health bar, and when the Pygmies throw the spear enough times at the T-Rex, it will die. You pick up the spear and give it to the islanders so they can throw it.
Edit: Thanks to Bob who reminded me that there is a Easter Egg in the new version of Pocket God. To find out what it is, highlight the following text:
Go to the original island and tap on the jewel on the statue a couple times. It will turn all the pygmies to ashes.
