Tooth Home

Tooth Home is the former residence of Georgia, and a location found on the island. It contains a bed, a locked cabinet with lamp on it and a picture above it, labelled poitraits of the island residents and text reading "I am tooth home. Collect bone and feed me. Drink from well to heal. Creature take you to another world."

Story
It is not known how Tooth Home arrived on the island. In IL08, Braxton asks if it grew from the ground, and says that according to Georgia Tooth Home is a living entity, and it is her passion to sustain it and see what will happen when it reaches full power.

The first people to arrive on the island, Georgia and Susanna, decided to make it their home due to its hollowness and warm temperature. As the writing on the wall suggested, creatures arrived and Georgia began to collect teeth for the Tooth Home, becoming obsessed and deteriorating her relationship with Susanna. One morning, magnifying glasses labelled 15-28 were found by Susanna in the Tooth Home, but an image found in them shocked her, so she chose to leave the island forever.

The first screen after loading into Illusion Lock mentions that the tooth home guides the seven residents of the island one at a time. Tooth Home is the first location we see in IL01, where Edgar explains its purpose and the need to collect teeth. It is well lit, and the picture above the cabinet portrays Sop's House, along with some flowers and the symbol of a secret truth. After all the teeth are collected in IL05, the cabinet is opened by Georgia, and the ending screen proclaims that "The tooth home will have a feast tonight!".

Usually, the bed only gives you music, however when Russell sleeps on it in IL08 he has a nightmare about a bear trap.

In IL13, Edgar explains that by guiding the characters, he is the Tooth Home, and has always been since day 1. After playing the tune found in IL05, Georgia exits Tooth Home to a new pathway leading to Sop's House, where she finds and collects Eleanor before escaping back to Tooth Home. Georgia tries to open the cabinet, which along with the rest of the home is seen only in black and red, but she cannot open it and is caught by Sop. However, Eleanor as the master key is able to open the cabinet, retrieving a bear trap and maiming Sop.

The group try to leave the island, but are stopped by a storm, forcing them to stay in Tooth Home until it passes. They remark that it is barely alive, and must be starved now that they know where it came from, Georgia being misguided in choosing to feed it. Tooth Home is now darker, and Georgia's poirtrait is surrounded by flowers. Outside of Tooth Home, an egg hatches into Georgia's soul, and the 7 island dwellers combine to form Yotis and defeat the final boss.

In IL19, the portrait of Sop's House inside Tooth Home has been replaced, as it was evil, and Georgia's soul has been placed in the cabinet, only to be opened in dire circumstances. When Eleanor returns to the home in IL21, the light on the cabinet is now glowing teal. Theresa's letter to Eleanor after she leaves says that the life within Tooth Home was replaced, and Eleanor is going to restart collecting teeth as before, but she will be feeding Georgia instead. After she leaves, her portrait has been removed from the walls.

The same happens to Braxton's portrait after he leaves, leaving only Georgia's, Chester's, Paisley's, Russell's, and Eleanor's. After Eleanor's game begins in IL27, one line appears under their portraits for each tooth lost. After six rounds Chester refuses to play and leaves Tooth Home, but after walking a short distance away, he runs back to Tooth Home chased by a large monster. Eleanor refuses to open it, leading to his death, and then kills Russell with a bear trap after he runs at her. Eleanor chases Paisley to the other side of Tooth Home, but Georgia's soul prevents her from attacking Paisley and knocks her to the other side of the home, allowing Paisley to attack Eleanor with her ice skate. Paisley exits Tooth Home as the storm ends.

When Paisley returns to the island in ILV05, Tooth Home looks the same as at the end of ILV27, including the missing portraits and blue light. When Ralph enters Sop's version of Illusion Lock in ILV07, the Tooth Home is very different, including a glitched interior and music. Upon re-entering Tooth Home at the end of ILV08, he collects a symbol.

Trivia
