Detective Pikachu: The Musical

I found the local lowlifes
Laying low inside their lair
"You crooks were at the crime scene
And you left behind your hair!"
"We tried to catch a Pikachu-"
"-until it went berzerk!"
"That alibi's not flying, pal
"Your story doesn't work!"
"I combed the place, believe me!
Not a Pika print in sight!"
"Perhaps he wore some Pikashoes
To hide them?"
"That's not right!"
"I need you to do better..."
"It was sallow-skinned and scary!"
"Then draw me what you saw
Because I think it killed Clefairy!"
"Eyes so cold and dead
And a tail that was crooked and jaggy"
"Cheeks were smeared and red"
Its physique was impressively saggy..."
In a rut!
Don't know what to do!
Call Detective Pikachu!
He'll uncover any clue
To solve all your cases!
He can sniff out a lie like that
In his cute super-sleuthing hat!
He's a tough little gumshoe rat
Who holds all the aces!
I paid a little visit
To my friend at Poké U
If a culprit was on campus
He would know exactly who
"I've got a couple questions
'bout a sinister transgressor."
"Are they a boy or girl?"
Asked the Pokemon Professor
"It's possible they're neither
Based on eye-witness description
This drawing's all we've got
To get our criminal conviction."
I asked him to examine it
And tell me all he could
"This picture," said Professor Oak
"...is not very good."
"Could this change your mind?"
"Yes, this image has gotten much finer!
This was well-designed by a Pokemon costume designer!"
In a rut!
Don't know what to do!
Call Detective Pikachu!
He'll uncover any clue
To solve all your cases!
He can sniff out a lie like that
In his cute super-sleuthing hat!
He's a tough little gumshoe rat
Who holds all the aces!
"Your twisted game is over, pal
I'm giving you one chance
To take that stupid mask off
Or else you and I will dance!"
Zubatman sulked a moment
Like his feelings had been hurt
"Well, since I'm feeling generous
I guess I'll spill the dirt
I solved this case already
So here's your final clue
The killer's costume
Was to MIMIC YOU!
At the scene
Did you check the ground?
Not a Pikachu print was found
Something else left its prints around
Betraying its gimmick!
Rocket's sketch seemed a bit obtuse
But it served to help me deduce
That the Pokemon on the loose
Was simply a Mimikyu!
