To soften the ice creams, I removed them from the freezer to sit on the counter for about 7 minutes before I needed to use them, but be mindful of your house temperature, it could be more or could be less.
I unwrapped the ice cream sandwiches beforehand, leaving them on the wrapper, returned them to the freezer and cut them in half before I was ready to use them. Those don't need to be softened.

1 ½cupsgraham cracker crumbs
6Blue Bunny Simply Premium Vanilla Ice Cream Sandwichescut in half
Spray the sides and bottom of the springform pan with cooking spray.
Cut a circle in some parchment paper by placing the 10-inch springform pan on top and trace around it. Place the circle into the bottom of the pan.
Cut a 2-inch strip or strips in the parchment so that the final length is about 33 inches to line the side of the pan.
In a medium bowl, mix together the graham cracker crumbs and sugar.
Add the melted butter and mix until well combined.
Pour the crumb mixture into the pan and flatten so that the bottom is completely covered.
Place into the freezer to harden for 20 minutes.
Assembling the Cake
Place the ice cream sandwich halves cut side down against the side of the pan.
Place the chocolate ice cream on top of the graham cracker crust and smooth with an offset spatula.
Spread 1/2 cup of the pineapple topping over the chocolate ice cream and top with a layer of banana slices (I used about 2 of them).
Place the cake into the freezer for at least 30 minutes.
Remove from freezer and spread 4 cups of the double strawberry ice cream over the banana layer and cover the ice cream sandwiches as well.
Place into the freezer overnight.
To Remove the cake
Place the springform pan upside down onto a plate or cutting board. Wrap two damp hot kitchen towels around the pan and allow to sit for about 15 seconds or so until the pan can easily be removed from the pan.
Put a cake plate or serving plate up against the crust and gently flip the cake with cutting board (plate, whatever you've used) so that it is now right side up.
Return to freezer for a half hour.
Spread the jar of strawberry sundae topping over the top of the cake and top with bananas.
Place the remainder of the pineapple topping over the bananas.
Top with whipped cream and maraschino cherries.
To slice, use a large hot knife. I found it easiest to submerge the knife in hot water and then wipe it off between cuts to allow for clean slices.
Serve drizzled with chocolate syrup and nuts, if desired.
