Splinter question.
 

If the mutagen cause a person to mutate into the last animal they came into contact with, & the last thing that Hamato Yoshi came into contact with was the rats/his pet rat, hence why he turned into the rat {via the cartoon},but, technically, were the turtles & the rats the last things he came into contact with, together? So, shouldn't he be half rat/half turtle?

The flashback narration clearly said, "Yoshi had most recently been with the rats."

If you're asking why didn't he become some sort of mutant hybrid of two animals....who knows. A better question is how Muckman and Joe eyeball mutated into garbage...when garbage isn't alive.

Theoretically, Splinter touched the turtles before they touched the mutagen, then would touch a rat next, and then touch the mutagen on TOP of the turtle (or next to the turtle) before touching the actual turtle. Thus, this is why Splinter mutated into a rat.

So, he touched a rat last, before touching the turtle, yet the turtle were covered in mutagen, as he touched them, yet he still became a humanoid rat, & not a hybrid?

As for Muckman & Joe Eyeball, maybe the garbage had some algae in it? But, what's that say for Mutagen Man?

Yeah, despite the mutagen being technically science, it seemed to function more like magic.:tgrin:

But if we are going by the cartoon then we see him step on the mutagen before he touches the turtles. So his mutation had already started before he ever picked up the turtles.

As for the other mutants that came out differently, the mutagen formula was never exactly the same as the original so it could have different results. We can find almost any logical answer in the cartoon.

I remember in "Invasion of The Punk Frogs" that it is said that there are four chemicals that combine to make the mutagen. In "Enter:Mutagen Man" the mutagen concotion that Shredder had in the vat was only three of them. It needed the Bindex-3 in order for a being to hold together after being in contact with mutagen.

One could argue that the flashback that we saw in the first episode wasn't in real time. It's the same reason that some people argue that the turtles didn't just immediately grow to full size as quickly as they did in the flashback.

+1 for the sensible thing posted all day!:tcool:

No the mutagen turns you into whatever animal you last touched, not the last 2 or 3 animals you touched or the animal you touch after touching the mutagen.

he stepped in the mutagen on his bare feet, so it's not like his first contact was when he picked up one of the turtles.

He touched a rat, then the mutagen thus he turns into a rat. That's all there is to it.
