Mivvi Ice Creams were made originally by Lyons Maid. They were an ice-cream centre with a fruit ice outer shell and were available in orange at first but later strawberry and raspberry were added as alternative flavours.
Walls made a similar lolly called a Split I think. I seem to remember this was also available in pineapple. Mivvis are still around, only now they're made by Nestle.
