Glitches

Head outside of the Slam City Jam.

You'll need moon gravity for this one. Head to Slam City Jam, jump into the stands, and head to section A or B (You'll see this on the staircase). Turn 180 degrees and walljump on the A or B part of the stair rail so you're on top of the staircase. Walk to section X, which is found between sections A and B. Once on top of section X jump in the dark blue strip between the stands. You're now in a lobby with doors that lead to a little area with the Vancouver hotel, 2-D cars, and two ramps.

Easter Eggs

Get eaten by chihuahuas

At the end of the Hawaii level go to the quarter pipe. Next to the pipe will be a lot of houses and you will hear a lot of dogs barking. Go on top of one of the balcony and change the camera angle to look down. You will see a tiny little dog running around the yard. If you fall it will say, "Death by chihuahuas" or "Mauled by little dogs".

Moscow Easter Egg

Go to Moscow and get onto the building (green tile roof) that would lead to a gap. On this building you should see a chimney with smoke coming out of it. Get off your board and hop into the chimney for a humorous message. Repeat this other times to see other messages.

Strip Club Fun

Have you seen the strip club in Tampa, and wanted to go in and have some fun? Well, whether you know it or not, you can. To get in, go through the top of the strip club (the roof is breakable just like the dome in Moscow where you and Eric have the doubles session). In case that confuses you, walk (or skate) up the staircase on either side or the club, and jump into the dome that serves as the building's ceiling. When you come in here, there is a strip pole and a girl giving two business-men a private show. This area also serves as a very small bowl. But, if you look carefully (or not) you will notice an imperfection in the back part of the bowl. This is actually a staircase into the strip club. Unfortunately, you don't actually go in. As soon as you enter through the secret passage, the game plops you at the entrance to the club (next to the two pole-dancing girls, in front of the bouncer), and displays a humorous message. Sorry, if you want to know the message, you'll have to figure it out (it's not that funny, just an extra thing in the game if you've done everything else).
