Re: how to get the diving knife for my sims 4 diver

@Avocadorica You don't need to follow them to work.
In Sulani, just zoom out a little and look around the ocean yourself, not as your Sim. As you look at the various areas of water you will see buoys floating, look for where dolphins are swimming as they often congregate around bouys. You don't even need your Sim to swim up to one to purchase the diving tools. Just click on them as you find them and it will show you the tools you can purchase. There are snorkelling bouys nearer and scuba diving buoys a little further out. You need to be one one of the bigger parts of Sulani, Lani St. Taz or Mua Pel'am to buy the best range of gear from the the scuba diving buoys.
