Baby bone spider

From Tardis Wiki, the free Doctor Who reference

A female baby bone spider was born in Alice Parsons' house sometime before November 2014.

She liked to sleep on Alice's lap listening to her lullabies.

When Alice Parsons died in July 2015, the little spider got into Alice's coffin and, unseen, was carried away and locked in Parsons' family vault in Kensal Green cemetery.

In November 2016, Tanya Adeola and Alan Turnpike found the little spider and returned her to her mother. Both spiders remained in the house until a way would be found to return them to their home planet. (PROSE: The Stone House)
