Its movement on the Ethereal Plane before coming back to the Material Plane makes it seem like it can teleport. Instinct: To preserve to eat later

Oh, what a harmless little thing! A rabbit sat atop a treet stump! That's what they want you to think my friends, but then some betentacled horror spears you with its barbed tendrils and drags you into its waiting maw! Anyway, and that today fellow councillors is why we should begin a program of destroying all stumps and killing all rabbits. Just in case. Instinct: To feed

Pterafolk (pronounced TAIR-eh-folk) are 10-foot-tall, winged, reptilian bipeds native to Chult. Malevolent isolationists, they regard most other creatures as their enemies. In Chultan culture, pterafolk are often referred to as "terror folk" for their habit of swooping down from the sky to snatch whatever and whomever they can, then transporting treasure and food back to their roosts. Pterafolk have 20-foot wingspans and give birth to live young. Ancient rituals once bestowed upon pterafolk the ability to assume the forms of pteranodons and wingless lizardfolk, but those rituals have long been forgotten. Instinct: To Spread Terror

• Dive Attack
• Fake Attack

Following a similar ecological niche as all manner of silly creatures that disguise themselves as something else, this particular one does not wait for someone to put it on. Obviously, since it looks like its namesake. Instead, it waits clinging to the ceilings or corners of ceilings and tries to get the jump on unfortunates wandering through its territories, feeding upon their remains. When in flight it flutters like a weird jellyfish in the air, which looks vaguely beautiful - so there's that at least. Instinct: To feed

• Wrap around someone's head and suffocate them
• Surprise them

What on earth would cause this mollusk-like creature to shape like a stalagtite? The urge to hunt of course. With this in mind, and given enough exotic environments, this creature could end up shaped like any number of things that might hang from the ceiling, such as a chandelier or similar. But who would keep these things around in their home? Wizards, who else? Instinct: To feed

• Drop on the unsuspecting
• Surprise them!

Sometimes you have to wonder: Is everything a trap? And if you have angered the right (or wrong) kind of wizard, then the answer is probably yes. Why else would the death linen exist? Masquerading as sheets, or pillows, or a set of clothes, or all of the above - this construct waits until its victim tries to wear or sleep on or otherwise interact with it before it tries to strangle and smother them. Efficient, and hard to pin down as a murder. Whimsical? Yes. Efficient? The jury is still out on that one. Another theory and/or origin of these is less whimsical: The power of living nightmares have suffused these, and they now linger and wait to terrorise and murder those that they (subconsciously) deem to be victims. A more compelling origin, but no less silly. Instinct: To kill

• Smother the unfortunate
• Surprise them!
• Use secret poison fangs that no-one would have guessed you had

You thought that was a mere wall? Foolish! Always be suspicious, after all if gelatinous cubes exist then what others gelatinous horrors might there be, masquerading as anything and everything. Its touch will corrode and incapacitate until those engulfed are horrifically eaten. Not a great fate, all in all. Instinct: To feed

• Engulf the unfortunate
• Surprise them!
• Paralyse with a touch
