If you enter the Skate A Rama arena from the west (not east) you'll be able to successfully finish this portion of the game. For some reason tryiing to complete this section of game after entering from the east will result in nothing but endless deaths. Hope this helps anyone else who had this issue.

Can anyone tell me how I'm supposed to get the code to get back to the mall in SQX? All the walkthroughs I've looked up just say "head back to the mall", but I have no idea how I'm supposed to get there.

It's been ages since I played, but if I remember right, the code to get to the mall is on the display when you first get in to the time pod in the mall (whoever was in the pod last had to type the code in to get to the mall, so you've got to look at what they typed before you type anything and erase it)
