what is malco and how did he make the boom from simple ingredients

it's not possible to make the boom from gum base charcoal and jellyfish
i think that malco use it to house the boom that he extract from his body (dragon ball z reference )
because one of his kind explode in the credits
and he is very panic robot
also i think thier kind of robots is responsible to manage the terminals in the egg corridor and that what made some of the eggs don't hatch correctly

 

I think this is how he made the bomb. I have no idea about the Jellyfish Juice, though

• Charcoal burns. Maybe Malco turned the charcoal into the fuse?
• Gum Base is probably very sticky, so he could be using it as an adhesive to hold it all together.
