Fighting fish and fern

My parents and my sister have left town for a week for a little holiday. Before they left they gave me the contents of their fridge (lamingtons,shallots, a leek, pumpkin, tomatoes, capscium, spinach, a single potato, cherry tomatoes, avocado) as well as my sister's fighting fish and my mother's maidenhair fern to look after. The food will be turned into tonight's dinner. The fighting fish, whose name is Jack (after Captain Jack Sparrow) and the fern have been placed in the bathroom. It is my duty to keep the bathroom door shut all week to prevent the cat from discovering their existence. The bathroom is the safest place but should worst come to worst I will be making trips to both the nursery and the pet shop before the week is over.
