Rippers Reef is
The Reef
a reef of the coast of Goo Lagoon. It appears in A Life in a Day. SpongeBob was trying to "live like Larry", something Patrick Star regretted attempting. He planned to catapult himself into the lagoon, not knowing the angle of trajectory would land them in the reef. It is a small island, with many purple spikes and shards sticking out of it. Larry tried to save them, but he came too late. They all ended up in the hospital. Spongebob wanted to land there.
