Biggol Sword

The Biggol Sword (originally called Biggoron's Sword in the legacy version of the game) is a valuable sword that the Toppat Clan has in its possession during Infiltrating the Airship.

As a sidequest during the game, Henry can try to find this sword, which is hidden in a chest in a secret room in the Airship. If the task is completed, the player gets an achievement.

Plot
Finding the Biggol Sword requires the player to perform multiple tasks in the game in the right order.

First, the player has to go through the "Pure Blooded Thief" pathway, using the Grapple Gun. Henry arrives in the surveillance room, where there is a gold key next to the computer. By clicking the key, the Key Get sign shows.Later, when he reaches the brig outside the vault, Henry uses the key to free Dave Panpa, the imprisoned security guard. When Henry breaks into the vault, Dave also briefly enters the Vault and drops a flash drive, which Henry picks up.

After the Airship crashes in the desert and the Center for Chaos Containment steps in, the flash drive can be seen in the drawer with four disks Wilson Stone must choose from. Clicking the flash drive reveals a code from Karl, which reveals the code 1-2-1-4.

When the game is finished or the player has returned back to the title screen, the player has to go through the "Government Supported Private Investigator" ending, choosing the Earpiece in the start menu. When Henry enters the ship by vacuuming Hatchman and then entering the ship, there is a keypad on the wall. By clicking it, Henry can enter the code he retrieved from the flash drive, which will open a door somewhere else in the ship.

Finally, the player has to go through the "Rapidly Promoted Executive"/"Relentless Bounty Hunter" ending by choosing the Cannon Ball. When Henry starts chasing Reginald through a hallway, he comes across the now open door. Curious, he will enter it and find the Biggol Sword in a chest.

Appearance
It can be assumed that the sword makes a return in Fleeing the Complex, in the "Presumed Dead" ending scene where Henry fights Karlov Chernik in a sword fight. The sword Henry uses has a blue guard, just like the Biggol Sword in ItA.

However, in The Henry Stickmin Collection, the Sword was redesigned to have a reddish purple guard in ItA, whereas the sword Henry uses in FtC remains blue.

Trivia

 * The name is a reference to a recurring weapon in The Legend of Zelda video game series, but it had to be renamed in The Henry Stickmin Collection for copyright reasons.
 * The sword was also redesigned for this reason. In the original release of Infiltrating the Airship, it looks exactly as it does in The Legend of Zelda series, but in the remastered version, the blue cross guard was changed to maroon and the goron symbol on the rain guard was changed to a Toppat symbol.
 * If Henry uses the Retroglove in the cells after releasing Dave, nobody is present to laugh at his expense.
 * The original flash version used The Ocarina of Time version of "Uncover Secret", "Open Chest" and Get Item".
 * In the remastered version, PuffballsUnited replaced them with his own versions to avoid copyright, and the song the game plays when Henry finds the sword is the same track that plays when the players use the shovel in the remastered version of Breaking the Bank.
 * The code needed in order to open the door to the sword is the date that PuffballsUnited joined Newgrounds.
