Detail [my] pets is an innate command that shows you the name and status (alive or dead) of your pets.
You are remembering the following pets: patches (alive). You take on the look of someone being mugged on Memory Lane.
Other players in the room will see the following:
<Name> takes on the look of someone being mugged on Memory Lane.
For pets that come with a name, such as tabby cats, this command is the easiest way to discover what the pet's name is.
