On snowboard cross there is bouncy pads barricaded in by signs. You probably already know this but just in case you don't here is a little help. When you get to the bouncy pads squeeze through the gap right into the side and you will bounce into the air when your in the air turn in (left or right depends what side your at,if at left side turn left and if at right side turn right)and you will land on the red banister. Ride on this banister and you will collect coins, press A , you will then go up and back down again when you collect coins again you will get another special thing before you use this one wait a couple of seconds then use. When you jump off turn into the middle and there will be a green board and a star coin thing time it right and you will get it if not timed right you will miss it. This is able to go left or right to get on the bouncy pads. Hope this is helpful!
In Dream gliding,in one of the sides of the area,You will See SANTA with his raindeer!!!!!You must get a note from him in the game to see him waving at you.Talk about christmas in winter games.TEEHEE! Have a nice time.
Be Yoshi then after you do the starting dash do the special button [a] while in midjump then get it again and don't use it wait until you get to the 3-way part go on the middle path don't grind on the first ramp jump perfectly and then use the A button in midjump and you will skip the 2nd Ramp! Thats a good thing to skip it because it will slow you down.
Thanks to my little brother, I got some more for you guys :D
Cream (Short Track): At the start area, there are a few TVs showing the action. Cream is flying infront of the right one. Penguin (Ski Cross): After the cannon shoots you, you will pass over some buildings. Penguin is on top of one of the chimneys. Chaos(Alpine): Sorry, but I'm not so sure about this one. Near the ending, we pushed minus, and got him somehow. I think he might be on top of the finishing arch, or the one before it. Birdo(Ski Jumping): Toward the middle of your jump, there's a pill-shaped thing with glass surrounding it. Birdo is at the top, in the dome.
PLEASE NOTE THAT I WON'T POST EASY TO FIND ONES, OR REALLY HARD-TO-EXPAIL ONES.
Chaos: One of the first letters/VIPs, he's in the tree on the right of the start ramp in Dream ski jumping. Big: In the Temple area near the boosters, there are two small platforms to each side of a tunnel. Big is on the left one. Birdo: Near the cannon, there's a stone fence to the left. Birdo's jumping on top of it. Cream(Dream Ski Cross, not hockey): Infront of the two warp pipes, not behind the start point, is a fence. Cream is on one of the picketts.
That's all I've found for now. If I find more, I'll let you know. :D
