The Rabbit Toy is an item that appears in Hello Charlotte Episode One and Hello Charlotte Episode Three.
Hello Charlotte 1[]
Teddy Bear House[]

In the first episode, there are two instances of the Rabbit Toy appearing. The first one is in the Teddy Bear House in the TV World, which must be given to Bunny Freya to proceed any further. To find it, make it into the kitchen that was being guarded by a killer Teddy Bear, then proceed to the corridor Bunny Freya is in (Back Door Key needed). Then head left and head to the room furthest down the hall. The toy rabbit is between the two bookshelves.
Hello Charlotte 1[]
The second Rabbit Toy appears in Charlotte's room after returning home from the TV World. When taken, it doesn't actually go into the Inventory, but Felix will be in the party; this is a subtle yet effective "secret" that reveals Felix was in actuality the stuffed rabbit the entire time.
Hello Charlotte 3[]
The Rabbit Toy in Episode 3 is given to Scarlett Eyler by Felix as a gift, which Scarlett promised to cherish. The item doesn't do anything, but it is presumably the very same Rabbit Toy Charlotte has in Episode 1; this is one of the many hints sprinkled throughout the second portion of Hello Charlotte 3 that implied that Scarlett and Charlotte are one and the same.
