|Spark Mandrill|

Sub Tank: It is located near the start of the level, you need the Boomerang Cutter from Boomerang Kuwanger to get this one.

Heart Tank: After the Miniboss, you'll come across a dark area and then a Mega Tortoise. After that is a staircase leading down. But climb up the wall and you'll find a small platform with the Heart Tank. Either wall jump or use Boomerang Cutter to get it.

|Launch Octopus|

Heart Tank: After the second submarine with the spike traps on the bottom, you'll come across a battleship on the surface of the water. Destroy it to reveal a hidden area underground. Destroy the Sea Snake there and get your Heart Tank at the other side.

|Flame Mammoth|

Heart Tank: Before getting this, make sure you have defeated Chill Penguin first as then all the lava will turn to ice and solidify, making it safe to walk across. At the end of a long area with platform and several Dig Labors, you'll find the Heart Tank there.

Sub Tank: In the same area with the Heart Tank, climb up to the top platform and go left, past the Mettools. Dash jump to the wall on the left and break the wall away to claim the Sub Tank.

Arm Upgrade: Before getting this, you must get the Helmet Upgrade from Storm Eagle's stage. Near the beginning, you'll come across a breakable ceiling. Dash jump to there and break it while climbing up to get it. It's hard, but possible. Alternatively, you'll get it automatically from Zero after defeating Vile in the first Sigma Fortress stage.

|Storm Eagle|

Heart Tank: At the very beginning of the stage, ride the platforms up to the top, then dash jump to the left. You'll come across a platform with the Heart Tank at the far left.

Sub Tank: Near the beginning, there will be pillars that rise up and down. Go up one and shoot the glass to destroy it. In it will be a Gun Volt. Destroy it and claim the Sub Tank behind it.

Helmet Upgrade: After crossing all the vertical platforms, you'll come across a climbable tower with criss cross metal bars. Climb up on top, then drop down to the right, destroy the flammable tanks and claim your prize. 

|Chill Penguin|

Leg Upgrade: You will automatically come across this one near the beginning. You literally cannot skip this one.

Heart Tank: After leaving the cave, you'll come across a Ride Armor. Jump on it, go forward, then jump up towards a platform above. You need Flame Mammoth's weapon to destroy one of the igloos there to grab the Heart Tank.

|Sting Chameleon|

Armor Upgrade: Near the beginning, you'll come with a fork in the road leading up, forward and down. Go up and defeat the mini-boss to make the capsule appear.

Heart Tank: Before getting this, make sure you defeat Launch Octopus to flood part of the level. Near the beginning, you'll come across a fork in the road leading up, forward and down. Go down and break the walls, then dash jump towards the Heart Tank.

|Boomer Kuwanger|
Heart Tank: This will be in plain sight near the end of the level. You will need Boomerang Cutter to claim this one though.

|Armored Armadillo|

Sub Tank: When you see the first wall-destroying tank, go behind where it was and you'll find the Sub Tank there.

Heart Tank: It will be located up a platform with the second wall-destroying tank. Either land in front of it and run and climb up the wall, or land behind it and destroy it before it destroys part of the wall leading up to it. If it does, you can't get it and will have to either die, or restart the level.

Secret Upgrade: This can only be gotten after getting EVERYTHING above. Make sure to have plenty of lives on hand as well. Go to the end of the stage, and as the last minecart reaches the end, jump up to a ledge above the boss door. The capsule is supposed to pop up there, but may not always be there. If it's not there, drop down and die, then try again. Repeat that until the capsule pops up and claim your secret prize, the Hadouken. To perform this, simply do the original Hadouken command from Street Fighter. This move is so powerful, it insta-kills everything, even bosses but can only be performed if your health is full.

So there you have it, the location of all the collectibles. Happy gaming!
