Cassette part or what?

[Baxters@large]

Just doing my annual(ish) poo tank clean when I came across this green filter cap rattling around inside the tank. Can’t see it on the parts lists so don’t think it’s fallen off. But how on earth did it get in there?
Ideas most welcomed.
Now gloves back on….

Doesn't look like part of the bog, probably fell in at some time.

You have been eating some strange food.
Nothing to do with the loo.

Had my cassetts stripped down a few time and not seen one of those.

Ask the other half if they are partial to eating plastic

You fit that at the bottom of the bowl if you have swallowed anything you need to retrieve

To me it looks like something to holder a deodoriser similar to what you would see in a urinal in a gents public loo

Is it a lid or dispenser for a cleaner/wash liquid you have used in the cassette?

Think it’s a superduperpooperscooper

Thanks all. Always fun on this forum.

Suddenly I know what it is. We put a de-humidifier in the loo over winter. It had fallen down and the cap must have gone down to hole! Glad it’s not a part as hate scrabbling around in there
