Barf and Belch / Biography

Barf and Belch is Ruffnut and Tuffnut's Hideous Zippleback.

Meeting the Twins and Ending the Dragon War
Barf and Belch were one of the captured dragons used to train the Viking Teens. The lesson they taught was to work together to find the head that lit up the gas (which was Belch). Later, Hiccup manages to get Ruffnut and Tuffnut to bond with them in time to help defeat the Red Death.

At the climax of the film, Ruffnut and Tuffnut, along with the rest of the Viking's teens, were on dragons. They helped the twins distract the Red Death to allow Snotlout and Fishlegs to attack them. By the end of the movie, the twins are seen riding Barf and Belch along with the other Viking Teens.

War with the Outcasts
It was revealed in the show that the left head's name is Barf and the right is Belch, with Ruffnut commanding Barf while Tuffnut controls Belch.

In, "In Dragons We Trust", Barf and Belch were framed by Mildew of the crime of stealing all the boots of the village during "boot night," sleeping in a bed of boots. They are then proven innocent by the comparison of their tracks and the tracks at the scene, noting how their tracks are deeper.

In "Twinsanity", Barf and Belch briefly went rogue after Ruffnut and Tuffnut's conflict with each other reached a point where they were issuing contradictory orders to the head they controlled. The Zippleback was roaming around the village just as renegade Viking chief Dagur the Deranged arrived to discuss a treaty. Wishing to sign the treaty in dragon's blood, Dagur captured and nearly decapitated Barf and Belch, but the twins were able to reconcile in time to help their dragon escape, with the other dragons faking an attack on the training ring to conceal Berk's newly trained dragons in order to avoid provoking war.

War with the Berserkers
Barf and Belch appear in almost every episode, appearing alongside or being ridden by the twins.

in "Zippleback Down", they accompany the twins as they attempt to dislodge hidden traps. When Tuffnut is captured, they are ordered by Ruffnut to watch over her brother while she attempts to go get Hiccup so he can free her brother. Although annoyed by Tuffnut's constant efforts to start a conversation with them, they end up playing with him (though Tuffnut didn't enjoy it much). They try to protect Tuffnut when a wild Typhoomerang (Torch) aggressively approaches him. Defending Tuffnut, they are caught in a bola-string trap, but they manage to cause a big enough explosion to start a forest fire somewhere off. They are freed by Hiccup when he arrives on Toothless and they ride Torch. The Zippleback end up helping to put out the forest fire and arrive back home on Berk safely on Torch's back. Later that night, when Ruffnut fails to free her brother from the trap and ends up with both of them being trapped, they leave their riders to bicker to presumably return home.

in "A View to a Skrill, Part 1", Barf and Belch help to free the Skrill from the ice block, along with Snotlout and Hookfang. The twins ride them and they help to snuff out the Skrill from the clouds so Hiccup can knock it down. They manage to save Hiccup from being blasted by lightning, although the twins and them end up being chased themselves. Barf and Belch manage to land safely on an outcropping of land in the middle of the ocean and help the twins go after Alvin when they see him collecting the Skrill. In "A View to a Skrill, Part 2", they are seen on Outcast Island being watched over by Ruffnut as Tuffnut and Hiccup try to gather information about the Outcast/Berserker alliance. They appear again later to help Toothless seal up the hole, trapping the Skrill in ice once again.

In "Cast Out, Part 2", they were seen in the end to both agreed together to separate their riders from fighting each other.

Founding the Edge
in "Dragon Eye of the Beholder, Part 1", along with their riders, Barf and Belch assisted Ruff and Tuff in worshiping Loki. During one of their pranks, they found Trader Johann. They then went with the other dragons and their riders to find Dagur at the Ship Graveyard. However, they were then scared off by the eels. However, they then returned to rescue Ruff and Tuff before they fell. In "Dragon Eye of the Beholder, Part 2", they helped their riders in obtaining a Snow Wraith tooth.

In "Imperfect Harmony", they were then drawn to Melody Island and captured by the Death Song. Luckily were freed by Hiccup. In "When Darkness Falls", Barf and Belch also discovered Tuff's new dragon, the Night Terror and captured the alpha night terror, Smidvarg. They then protected him until he was back with his flock. In "Big Man on Berk", they assisted in relocating a Scauldron from Berk's fishing lanes.

Participating in Dragon Racing
Bar and Belch then helped the other dragons and their riders in catching Silent Sven's sheep. They took part in the first two dragons and the official first one in which their riders cheated.

War with Drago Bludvist
Barf and Belch briefly appear being ridden by their riders, Ruffnut and Tuffnut. Barf in particular shows annoyance and slight aggressiveness when Snotlout approaches Ruffnut to flirt with her. Later on, they were also seen to be very upset about Stoick's death before being controlled by Drago's Bewilderbeast. Like all the dragons, Barf and Belch broke free from the Bewilderbeast's control, and acknowledged Toothless as their new Alpha. They then rejoin back to their owners, with both heads trying to comfort Ruffnut. Belch was rejected by Ruffnut, but Tuffnut quickly grabbed his head to be happy to rejoin together.
