Rioting otters caused chaos at Birmingham's National Sea Life Centre after escaping from their enclosure and desecrating a new attraction.
The five Asian short-clawed otters - Berry, Mango, Kiwi, Apricot and Pumpkin - caused chaos in the new Amazon section, overturning tins of paint and emptying jars of screws.
Keeper Vicki Griffiths had been trying to feed the animals when they made their escape, causing disruption to contractors busy creating a rainforest in a large indoor section.
Ms Griffiths said: "What followed was absolute anarchy. They emptied jars of screws and scattered them all over, climbed the artificial trees and wrecked part-constructed branches and foliage, and even up-turned a couple of tins of green paint."
The mischievous otter sisters totally ignored all desperate attempts to distract them and usher them back outside.
"They ran me ragged for about half an hour until I was joined by other members of staff and we finally managed, with the aid of tasty bribes, to get them under control again," Ms Griffiths added.
She said staff helped contractors to clear away the debris and recreate the feature.
"When the contractors came back they were nearly in tears. Happily they've virtually finished it now and it looks fantastic. We've let the otters back in and they seem equally impressed, if not in the least shamefaced about the trouble they caused."
The tropical facelift to the otter enclosure will help it blend in with a new Amazonian feature launching next month, featuring razor-toothed piranhas, electric eels and poison dart frogs.
