Ms Squirrell said: "I just got this idea in my head, because they are right outside the post office, and I thought, 'what if that was a little writing space?'
Emma works from a tiny office known as the spider milking room. On a typical day, she milks - or extracts the venom from - 80 of these Sydney funnel-web spiders.On three of the four walls there are floor-to-ceiling shelves stacked full of the arachnids, with a black curtain pulled across to keep them calm.
The remaining wall is actually a window. Through it, a small child stares, both fascinated and horrified, as Ms Teni works. Little do they know that the palm-sized spider she's handling could kill them in a matter of minutes."Sydney funnel-webs are arguably the most deadly spider in the world," Emma says matter-of-factly.Australia is famously full of such deadly animals - and this room at the Australian Reptile Park plays a critical part in a government antivenom programme, which saves lives on a continent where it's often joked that everything wants to kill you.
While the quickest recorded death from a Sydney funnel-web spider was a toddler at 13 minutes, the average is closer to 76 minutes - and first aid gives you an even better chance of surviving.So successful is the antivenom programme here at the Australian Reptile Park that nobody has been killed by one since it started in 1981.
The scheme relies, however, on members of the public either catching the spiders or collecting their egg sacs.
In a van plastered with a giant crocodile sticker, each week Ms Teni's team drives all over Australia's most famous city, picking up Sydney funnel-webs that have been handed in at drop-off points such as local veterinary practices.Vaccination will start in August and will be offered through sexual health services.
Public Health Scotland said it was also working on plans to launch its own programme for high-risk individuals.Northern Ireland's Department of Health said the issue is being considered, with an announcement expected shortly.
BBC Newsbeat has also asked health leaders in Wales whether they intend to do the same.This vaccine wasn't designed for gonorrhoea. It's the meningitis B vaccine currently given to babies.
