I remember Quattro... I used to quite like that.
You can still get tutti fruttis, the bag is smaller and they're not as chewy as they used to be but they're definitely there in the corner shop... purple packet probably near the jelly tots.
Treets and M&Ms are two different sweeties... the makers ditched Treets to make way for M&Ms according to a google search (so it must be true).
Can you still get fruit polos???
