When the Spelunker is swallowed by the Worm, they encounter many juvenile Worm Babies as they make their way through the body of the colossal adult.
Worm Babies are numerous in the level, but are also very weak.
They can be a problem in narrow tunnels or when they are above you, as they move fast and will crawl off ledges to chase the Spelunker. They may inadvertently crawl onto spikes or get trapped in pits, as they cannot jump.
Three Worm Babies are released from Worm Eggs when they hatch.
