Twigs is easily recognized as she has a paralysed right arm – the result of a traumatic accident that occurred prior to her rescue. Due to her weakness Twigs is a shy animal and on arrival at the LWC she was seriously dominated by Brighter, with whom she was rescued. However after being introduced in quarantine to Anthal and Arno, Twigs became very playful and was able to regain confidence through the contact with the other gorillas. She is sometimes bullied by Chella though, but when this happens all the other gorillas rush to her defence. Twigs can often be seen bathing in the pool.
