I remember 'pacers' they were white mint squares (exactly like opal fruits) but with 3 green stripes across em.  - but i weren't keen on them, I did like spangles, but my fave 
 
 was the pyramint.  It was dark chocolate triangle pyramid with white mint fondue centre.. Mmmmm making my mouth water.
 
 I wish they did a cadbury fruit bar though, you know like fruit and nut without the nuts though, i rememember writing to them once, ask them to do one, for people like me who hate nuts in choc, or for allergies, apparently they did a 'just sultana' they told me but wasn't successful.
 
 Shame... I bet it would be now...  Cadbury's is the best!!!!
