However, there are a couple of things to consider:
* The Yellow Spotted Lizards: These lizards are mentioned as being poisonous, but their venom isn't stated to be lethal. Stanley Yelnats gets bitten by one, and while it is painful, he doesn't die.
* The Warden's "Deadly" Kisses: The Warden is known for her "kiss of death," which involves her biting people. This is more a metaphorical threat to enforce obedience, rather than an actual deadly bite.
Overall, while the book has some dangerous elements, including the harsh conditions of Camp Green Lake and the potential for violence, there aren't any bites explicitly stated to be deadly.
