The Enchantment is an event for half-term and Halloween.
Children (and adults) have to "save the zoo" and collect secrets from the nocturnal animals.
Now, being the cynic, I'd much rather see this area returned to aviaries, but I actually quite enjoyed the whole experience and had a smile on my face throughout. Without giving too much away, the best bit was the girl pretending to be an aardvark, who looked uncannily like one and was having trouble staying awake.
