Hint: Easy kills:
If you have the Multirang and have to fight a group of Frills, run around in circles while throwing all of your boomerangs at once.

Hint: Cricky's Cove: Defeating the shark:
At the bottom of the cove are scuba tanks with air leaking from them. Hit it with your Aquarang so that it floats to the surface. The cement platforms are low enough for you to grab on to. Jump up. When the shark has the tank in his mouth, throw your Flamarang at it. This will make the tank explode, hurting it. Repeat this until it is defeated.

Hint: Rainbow Cliff: Easy lives:
Whenever you return to the Rainbow Cliff area from another area, there is a free life icon that you can pick up. Follow the dead end gully that is to the right of Julius' lab. The icon is at the end. You can go back and forth from any level to Rainbow Cliff as many times as desired to get this free life every time.

Hint: Ship Rex: Thunder Egg:
On the part were you must get the Thunder Egg for Ship Wreck, there is a hole in the wall by the anchor. Look in the hole and throw your boomerang at the button. The cargo door will open. Swim in and get the Thunder Egg.

Hint: Snow Worries: Crossing ice:
Go to where the very thin ice is when getting the Golden Cog. Walk as slowly as possible and the ice will not break.

Hint: Snow Worries: Getting the cog on the ice:
When you get to the cog, enable the "Elemental Bomerangs" code, then break the ice. Before the water freezes back, switch to the Frostyrang and shoot them at the water. They will make little ice floes for you to stand on. Keep doing this until you get to the cog.

Hint: Two Up: Frill kill:
When you have to get the Thunder Egg, collect over 100 Opals then go by the Frills (but not too close). Hold Bite and wait until Ty starts to turn blue. Then, point Ty towards a Frill and release Bite. Ty will kill all the Frills.

Hint: Defeating Bad Ty:
Use Frostyrang. When it breaks, he will lose life when he is on the floor.
Shaweta Walia.

Hint: Defeating Fluffy:
Switch to your Flamerangs and get behind one of the flamethrowers on the sides. Watch out for him hitting you. Aim at a part of Fluffy that you have not burned yet, and shoot him through the flames. If done correctly, he should burn down to metal.

Hint: Finding items:
Look behind waterfalls. There is usually an item hidden there.

When missing something in a level, just run around. When Ty sees something of interest, he looks at it. While he does this with checkpoints and signs, he also does this with Thunder Eggs, Bilbies, and Cogs. The only things he does not seem to look at are orbs and the boxes that contain them.

Hint: Warp Stone:
The Warp Stone affects the behavior of a Rang chassis. When added to the Doom chassis it will behave like a normal rang except that it has extremely long range.
Mick Ingram.

Hint: Last Rainbow Scale:
Enable the "Show objects" code. You will see a green line above the talismans. If you go to the gate across from the pillar and look at the pillar's back, the green line will appear. Go onto the ledge on the side of the pillar, then glide to the back. If you are in the correct location when you land, you will be on the ledge you saw when you were next to or in front of the gate to the Boss portal. Go to the end of the tunnel and you will find the hidden last Rainbow Scale. If it is the last scale, you will get a special prize from the Bunyip Elder.

Hint: Buying boomerangs:
To Buy boomerangs you must first gather Opals, the little red stones that fall out of Frills. Note: The Flamerang is useful against the enemies who hit stones at you.

Hint: Dennis flips the finger:
In the Bridge On The River Ty level, lead Dennis the Cheapskate to his home. When there, go into Ty's view and throw a lot of Kaboomerangs at Dennis. After awhile, Dennis might give you the middle finger.

Glitch: Fly:
When in any level and you see a picnic basket, jump up in the air and bite at the same time. Do not move once you are in the air or you will fall down. However, you can throw your Rangs in the air.

Glitch: Zoom in without Zoomerang:
Switch to Zoomerang, then go to some area that is clear. Throw the Zoomerang, then zoom in. While zoomed in, switch to another 'rang. You can then zoom in with that boomerang, until the Zoomerang returns. When the Zoomerang does come back, it will be stuck at whatever zoom it is at. Also. if you switch out of zoom in/out mode the camera is zoomed in on Ty's head. To get it off his head, just switch boomerangs.

Glitch: Drown Frills and bring it back:
Make a Frill chase you into the water. When the Frill is underwater (nothing sticking out), in a few seconds it will disappear then reappear on land.

Glitch: Ship Rex: Upside down level:
Go to the Ship Rex level. Get to the part where there is a sunken ship. Stay under water when you enter the area and swim toward the yellow rock into the wall. Return to the surface. Swim against the wall, and eventually you will end up going through it. You will now be in an upside down world. You can swim around, but you can only go underwater in certain locations. To stop this effect, exit the level.

Glitch: Ship Rex: Stuck in mountain then headless:
Start climbing Danger Spike. When you come reach a large dent in the mountain, jump into it. Push around in there, bite, or throw a boomerang. The screen will soon turn black. You may be able to jump, bite, or a throw a rang once, but other than that, you cannot do anything but pause the game. Pause game play select "Exit Level". After returning to Rainbow Cliffs, in short time Ty's head will disappear. Enter another level to return to normal. Note: This can also be done by diving into the water at the start of the Ship Rex level and hitting one of the rocks just precisely. [Video]
