Superfluous

Visited Granny B for a late 80th birthday 'party'.
Yesterday, whilst out shopping, B bought her some lovely Tulips and this. We managed to sneak it under her so we all had a good giggle. We all thought it would be a good item for Granny B to take to the over 50s club. Unfortunately Tilly jumped on it and burst it.
It'd probably be superfluous at an over 50s club anyhow.
