Happy Halloween~
Trick so Treat~ I gave you a treat, so now I'm going to play a prank~
...I have no interest in such things.
I don't really need any treats...
Trick yet Treat!! Forget the treats, I just want to play a prank!!
Trick or Treat...! If you don't give me a treat, I'll play a prank...!
Trick but Treat~ Even if you give me a treat, I'm still playing a prank~
Trick and Treat~ If you give me a treat, I'll play a prank~
Trick yet Treat~ Forget the treats, I just want to play a prank~
Trick so Treat~ I gave you a treat, so now I'm going to play a prank~
