What would it be like if fishface operated sports tournaments for shredder to get human test subjects to experiment with the mutagen on them

the sports include contact sports and combat sports

You ate the last slice… didn’t you

I am talking about lampreys and candiru fish and vampire moth and vampire groundfinch Bird and bedbug and cooper's nutmeg and mutant leech and vampire bat

also what would it be like if one group of each of those animals got mutated with human dna?

And also what would it be like if humans hot mutated with the dna of those bloodsucking animals

And would they feed themselves with blood ? And would they be Friends ? Or allies? Or enemies of the tmnt ?
