I loved the first one, and i love this one too!
Just about anytime you tried to make a joke i laughed at it. My favourite being the snake intro joke, a pure classic right there.
As said before, the animations are somwhat stiff, (most of the song dances were a pain to the eyes) not that you need to further break down limbs into seperate graphics, try to make thing wobble a bit more, its not manditory to have the arms be exactly were they need to be. and you dont always need to have joints 110% attached to eachother during movement.
I'm seeing new faces this time around (conker, mario bros, cloud) but subtracting faces from the previous episode (kirby, sub zero and scorpian, 3 out of the 4 ninja turtles). I suppose some characters were thrown in with no real intention of playing an active role huh? but, if youre suggesting new characters to show up shouldnt you make sure you can use the ones you already have?
Still, awesome job. Cant stop laughing/wathcing it because it always remains fresh and unpredictable.
