Helicopter

The helicopter is a red bubble helicopter with yellow stripes on the side. It is often used when Chris needs a good aerial view of something. The helicopter is one of the few vehicles that has appeared in every season of Total Drama thus far and appeared the most out of all the vehicles (twelve times), not counting the RCMP's helicopter.

Up the Creek
The helicopter's first appearance was in Up the Creek, when Chris flies over Boney Island to observe the two teams as they build signal fires. When Izzy tosses her fire-starter into the fire, the instant explosion blows the helicopter aside, but apparently does not harm it.

Trial by Tri-Armed Triathlon
Chris uses the helicopter to rudely wake up the six remaining contestants, then does a recap of the last sixteen eliminations, although for Owen, who was having a dream about donuts, cheese, and other sweets at the time, the sound plays right into his dream for a moment when he sees the helicopters carrying massive donuts beneath them.

Total Drama, Drama, Drama, Drama Island
Chris used the helicopter to observe the campers' actions from the air. In the beginning of the special, he watched as Lindsay, Beth, Geoff, and Bridgette walked right under the case while it was hanging from a tree branch and failed to notice it (although Ezekiel did see the case, Lindsay and Beth ignored him). As Bridgette and Geoff were making out underneath the case like it was a mistletoe, Chris was seen leaning out the side of the helicopter while Chef was flying it, and exclaimed, "okay, this is ridiculous!" Later, when Owen, Cody, DJ, and Tyler did see the case, Chris, still in the helicopter, yelled, "Finally!" At the very end of the special, after fourteen of the campers ended up in the lake and the case was eaten by a shark, the helicopter, still flown by Chef, swooped down over the Dock of Shame to drop off Chris before taking off again.

Alien Resurr-eggtion
Towards the end of the episode, when Duncan, Gwen, and Trent were the only ones who made it out of the alien ship set with alien eggs, Chris swooped in overhead in the helicopter, declaring that he was the "military" who had to prevent them from getting the eggs back to base camp. He then pressed a button that dropped two huge missiles full of slime right into the Western town set that they were in, which exploded on impact and sent slime all over the place. Chris barely avoided getting slime on himself by closing the door just as the wave of slime that had flown up into the air splattered all over the helicopter. He successfully hit Duncan, but Gwen and Trent survived the blast and walked away slime-free and with the eggs.

Celebrity Manhunt's Total Drama Action Reunion Special
The helicopter was not seen again until the final episode of the season. When the entire Total Drama cast (along with Sierra and DJ's mother) are chasing after Alejandro's bus in their bus, Chris and Chef decide to follow them in the helicopter, filming the chase the entire way. When the cast's bus flew off a cliff, Chris considered calling for help, only for him and Chef to laugh hysterically and leave. However, Chris ultimately decided to save them after all, and returned later by himself, attaching a cable to the overturned bus and carrying it all the way back to the abandoned film lot (which proves that the relatively small helicopter is actually very strong) with Owen, Gwen, Heather, Duncan, Leshawna, Izzy, DJ, Lindsay, Bridgette, Harold, Courtney, Cody, Tyler, Noah, Ezekiel, and Sierra all inside. Thus, these sixteen cast members all got to participate in Total Drama World Tour.

Chinese Fake-Out
Chris uses the helicopter to monitor the contestants' progress as they race along the Great Wall of China. For the second time in the series, the Helicopter narrowly misses a massive explosion during the challenge; this time, it was from a land mine that Courtney ran over, which sent a charred Courtney flying past the Helicopter at one point.

Awwwwww, Drumheller
The helicopter was Chris' "Emergency Kit" for when the Total Drama Jumbo Jet was accidentally blown up by Sierra. He and Chef Hatchet boarded the helicopter, much to the chagrin of the final three when it was proven to only be a two-seater.

Planes, Trains, and Hot Air Mobiles
Chris and Chef continue to follow the progress of the final three (along with "cling-ons," Sierra and Ezekiel) throughout the episode. At one point in the episode, Cody and Sierra's makeshift hot air mobile nearly crashed into the helicopter from behind, but the helicopter ducked just in time. Cody angrily told Chris and Chef to watch where they were going. When a sudden hail storm hit, Chris and Chef were kept perfectly safe and unharmed by the hail due to the glass covering of the helicopter, while the contestants were mercilessly pummeled.

Bigger! Badder! Brutal-er!
After the larger, more luxurious cabin was blown up by the Mutant Maggots, the helicopter appeared overhead, dangling the other original cabin from a mechanical claw below it. It dropped the old cabin down onto the spot where the new one had been, much to the campers’ chagrin.

The Treasure Island of Dr. McLean
The helicopter was used again when Chef and Chris swooped in over the two teams as they arrived at the beach and declared the Maggots to be the winners of the first half of the challenge. A newly-mutated Dakota tried to jump up and grab the helicopter so that she could attack Chris, with Chef barely managing to pull up before she could reach them. They also used it to block the Rats' path long enough to give them their handcuffs as their penalty for losing, and monitored the teams' progress from the helicopter for the rest of the challenge.

Grand Chef Auto
Chef flew in low over the helicopter to drop a massive block of cement onto the former Maggots' cabin, smashing it and forcing all of the contestants to share one cabin due to the merge occurring. Chris grabbed onto a rope ladder that Chef dropped down just as he flew off, with Chris smacking into the block of cement as he flew off.

Brain vs. Brawn: The Ultimate Showdown
The helicopter, piloted by Chef, flew in low over the stadium and dropped the pile of junk for Cameron and Lightning to use in the final challenge.

The RCMP's helicopter
The Royal Canadian Mounted Police Helicopter appears in Up the Creek, when the RCMP arrive to arrest Izzy. It is a large blue and white helicopter equipped with a search spotlight. It chases Izzy away, effectively eliminating her from the game and possibly sparing Lindsay from elimination that night.
