Halve bananas, then cut into quarters. Place 3 segments into each serving dish. Using a melon baler to achieve "tiny" scoops, place a scoop of each flavor of ice cream on top of the banana. (Ice cream may be scooped ahead of time and refrozen. This will help the ice cream to hold its shape.)
Drizzle a little bit of each sauce over the ice cream and sprinkle with crushed nuts, whipped cream, and top it off with a maraschino cherry.
Break up or chop the chocolate and place it in a bowl. Melt in microwave on low power, stirring every 30 seconds. Serve immediately.
Using a fork, mash strawberries with sugar in a bowl until well mixed. Refrigerate until ready to use.
Puree pineapple and sugar in food processor or blender until slightly chunky. Refrigerate until ready to use.
