The slasher took off the mask to reveal Yoshi was the one wearing the mask.
"Y-Yoshi, but how, why, i was told you were dead" Bowser Jr. said in fear as Yoshi kneels down in front of Bowser Jr.
"That's what i wanted you to think, the princess won't be able to save you now, nobody can" Yoshi said.
"You're not gonna get away with this" Bowser Jr. snapped before spitting in Yoshi's eye as he wipes the spit off before slapping Bowser Jr. in the face as he fell onto the floor.
"Never fucking do that again, disgusting disrespectful toerag" Yoshi said to him before walking out of the cell and closes and locks it.
"Enjoy your new life in here, the rest of your life that is" Yoshi said to him before laughing and walks off while putting his mask back on as Bowser Jr. lies down and starts to cry.
The slasher enters a room and looks at CCTV footage to notice it was empty.
"Perfect, not a sight or sound, now to pay a girlfriend a visit in the prison" the slasher said to himself before walking off and then jumps into a warp pipe as Peach was seen on the CCTV cameras sneaking towards the castle.
Birdo was seen in a cell throwing a tennis ball at the wall as it bounces off it back at Birdo as she catches it.
"Birdo" a voice whispered as she looked up to notice Yoshi at the cell window.
"Oh Yoshi" Birdo said to him before the duo kiss each other on the lips before breaking up the kiss.
"Did you kill everyone else yet?" Birdo asked.
"Not yet, i left Bowser Jr. to rot in a cell, and the princess is still roaming around, she's the last one left standing" Yoshi replied.
"Well then, we better go and find her then" Birdo said as Yoshi pulls out a chainsaw and cuts open the bars blocking the window and rips them off as Birdo climbs through the window.
"Hurry, we better get out of here before security comes" Yoshi said to Birdo who nods as the duo ran off together.
Peach wanders down the castle corridors while holding her gun and looking around and notices a door saying cell and then opens it up to reveal a corridor with cells.
"Who's there?" Bowser Jr's voice shouted out as Peach then entered the room and then ran down the corridor while looking into each cell and stops in front of one to notice Bowser Jr. sitting down in a cell.
"Junior" Peach said to her before Bowser Jr. looks up at Peach with a smile.
"PRINCESS!" Bowser Jr. said to her with a smile before running up to the bars.
"Oh i'm so glad to see you" Bowser Jr. said to her.
"Yeah i know, now get back and cover your ears" Peach said before aiming at the lock as Bowser Jr. backs up and covers his ears as Peach fires at the lock multiple times, breaking it as she opens up the cell as Bowser Jr. gets out of it as the duo hug each other.
"I thought i lost you…" Peach said to him before the duo break up the hug.
"Where's the slasher?" Peach asked.
"I don't know where he went, but i know who it is now, it's Yoshi" Bowser Jr. said.
"Yoshi is the slasher, no, but he can't be, this isn't like him, besides he's dead, Mario & Luigi found his body" Peach said.
"That's what he wanted you to think, come on let's get out of here before he comes back" Bowser Jr. said as Peach nods and picks up Bowser Jr. and ran out of the cells corridor before running down the main corridor.
Yoshi & Birdo walk out of the warp pipe in the CCTV room.
"And now, let's make some wild love" Yoshi teased before Birdo giggles as the duo fell onto the floor while kissing as Birdo looks up at the CCTV cameras to notice Peach running down the corridors while holding Bowser Jr.
"Yoshi!" Birdo said breaking up the kiss as Yoshi looks up at the CCTV cameras to notice Peach as the duo got up and look at the screens.
"FUCK!" Yoshi shouted out in anger before slamming his fist down onto the desk.
"How did she get in here, never mind that, Birdo get down there and take care of them, it's time to finish the task at hand" Yoshi said.
"I'll do anything for you sweetie pie" Birdo said before kissing him on the cheek before running off as Yoshi looks up at the CCTV cameras.
Peach & Bowser Jr. ran down the corridor before stopping.
"The exit shouldn't be far from here" Bowser Jr. said to her before gunshots were heard as the duo hide behind cover as the person shooting at them was revealed to be Birdo.
"Hey princess, how you doing?" Birdo shouted out to her.
"Why don't you come over and find out" Peach said to her before a gun points at Peach's head as she looks up to notice Birdo holding the gun at her head.
"Now let's finish this" Birdo said before firing the gun but no bullets came out.
"Out of ammo, bad luck bitch" Peach taunted before Birdo threw the gun at Peach in anger as she dodges before Birdo rammed into Peach as the duo went through the window and fall out of it with a scream as Bowser Jr. looks out the window with fear on his face.
