Cut pineapple in half. Cut out fruit but leave a rim of approx. 2-cm/1-in. on all sides. Slice fruit.
Peel and slice kiwis and banana. Wash raspberries and blackberries. Peel and halve papaya, remove seeds, and cut into equal-sized pieces. Using a spoon or a melon baller, cut small balls out of the watermelon.
