Roughly chop the chocolate coating and melt it over a warm water bath, stirring several times. Remove from the stove and let it cool down a little. (Should still be liquid, but already put on).
Peel the skin off the bananas. Halve the bananas. Prick a straw deeply at the cuttings. Cover a board with baking paper. Cover bananas on the stem with the couverture one after the other, let them drip off and lay them on the baking paper.
Decorate as you like with chocolate crunchy beads or sugar eyes. Chill for about 1 1/2 hours.
