Spring Bonnie is a character from the VR video game Five Nights at Freddy's VR: Help Wanted. He seems to be malicious software within the game that takes the form of an anthropomorphic rabbit and watches the player as they progress.

Five Nights at Freddy's VR: Help Wanted
Spring Bonnie first appears near a doorway in the main hub after collecting one the cassette tapes hidden throughout the game. By finding more tapes, Spring Bonnie will get closer to the player and become progressively more solid. The tapes imply that Spring Bonnie first entered "Freddy Fazbear's Virtual Experience" after old animatronic programming was scanned to create advanced AI systems. He began to greatly unnerve beta testers by watching them play, causing one of them to document what they knew about the abnormally in hopes another development team could find a way to eliminate it.

She managed to hide her documented recordings within a protected part of the game's code; in a place where only beta testers would look. However, Spring Bonnie then latched his programming onto the audio files as a way to prevent himself from being deleted. The female tester decided to fragment her recordings and scatter them in the form of tapes to protect the rest of the game from Spring Bonnie. In her final recording, the beta tester tells the player of a very risky way to possibly purge Spring Bonnie from the game. She reveals that Spring Bonnie is capable of possessing the player, and they would need to activate a switch somewhere in front of the stage while their body is being merged with the rabbit.

In the final level "Pizza Party", the player must navigate through maze using clues presumably left by Spring Bonnie. They are lead backstage where Spring Bonnie can be seen gesturing the player to follow him behind a curtain. Doing so will leave the player on the main hub's stage as Freddy Fazbear while the credits roll and Spring Bonnie dances in the background.

After collecting all the tapes, Spring Bonnie will attempt to possess the player next time they start up their game. If they take too long following the last tape's instructions, Spring Bonnie will successfully merge with them and the player will receive a game over.

If the player follows the instructions correctly, they will be locked behind a steel door while Spring Bonnie tells them to hush through a slot before disappearing. The player is then sent back to the main hub to find a glitching green Spring Bonnie plush next to them.
