Hmm.
As soon as the execution started, 2 tigers were shown in the edge.
And at the end, Mondo turns into butter.
And then, Monokuma or something puts the butter on a pancake and eats it.
This reminds me of the story of "Little Black Sambo".
Basically, Little black Sambo Goes out. He meets 4 hungry tigers and gives them his new colourful clothes, shoes, and umbrella so the tigers won't eat him.
Soon, the tigers have an argument about who is the most well dressed.
The tigers chase each other round and round from a tree.
This round and round reminds me of how Mondo was spinning on the cage time of thing.
Then, The tigers were chasing each other so fast that they turned into butter.
Little black Sambo took his clothes back and took the butter back home.
His mother then makes pancakes with it.
