Mother spider (Arachnids in the UK)
The mother spider was a large spider who grew because of toxic waste dumped at Jack Robertson's hotel.
This creature began life as a test animal in Dr Jade McIntyre's experiments. The creature was bred to be longer lived and have stronger webs than a normal spider to harvest the benicial charecterisitcs of arachnids.
When it was belived the subjected had perished, the body was improperly disposed of and dumped in a landfill polluted with toxic waster materials. The was mixed with the spider's alter biology causing it to grow larger and produce a large brood of young.
Eventually the mother spider became so big it began to suffocate, as it could not absorb enough oxygen, even in a ballroom inside the hotel. When the Thirteenth Doctor, Yaz, Ryan, and Graham with Dr Jade McIntyre went to deal with it, they realised it was dying anyway, and Jade stated the spider was more afraid of them than they were of it.
Robertson shot and killed it, much to the anger of everyone present. (TV: Arachnids in the UK)
