Explosive Entomology: Unveiling The Guppy Fly Mystery

Guppies are small freshwater fish that are often kept as pets. However, there have been several reports of guppies exploding, with owners finding their fish stuck to the filter intake with their intestines trailing out from a clean hole in their abdomen. This phenomenon has been attributed to various causes, including intestinal parasites, genetic abnormalities, constipation, and swim bladder malfunction.

On the other hand, Guppy is also the name of a transformation in the video game The Binding of Isaac. In this game, Guppy is considered a powerful transformation as it allows players to fly and generates flies that do double damage whenever a tear hits an enemy. These flies can be spawned by familiars, which are small companions that follow and assist the player character, Isaac.

Guppy flies do twice the tear damage

Guppy flies are a feature of the video game The Binding of Isaac. When a player's character transforms into a cat, they gain the ability to fly and will produce blue flies every time an enemy is hit with a tear. These flies do twice the tear damage of the player's character.

The guppy transformation can be achieved by collecting three of the following items: Guppy's Head, Guppy's Paw, Guppy's Collar, Guppy's Hairball, Guppy's Tail, Guppy's Eye, or Kid's Drawing.

Guppy flies are extremely useful as they deal double damage. They have your back covered against enemies approaching from the back or sides while you're focusing your fire on another target. Once your damage stat is high enough, they'll seek out and kill anything that comes near you. With 50 of them, most bosses go down without getting to do anything.

Guppy flies do 2x tear damage, so it doesn't really matter if you have a high rate of fire or high damage.

Guppy flies are generated by familiars

Guppy flies are familiars that orbit around Isaac and rush towards nearby enemies, dealing damage and dying in the process. They deal double Isaac's current tear damage. Guppy flies are generated by familiars.

In the Binding of Isaac: Rebirth, familiars are small companions that follow and assist Isaac. They are usually generated by passive items. The effects of familiars include pickup generation, shooting familiars that fire their own tears at enemies, and orbitals that act as projectile shields or deal contact damage.

There are different types of familiars, including temporary familiars, pickup generation familiars, shooting familiars, wandering familiars, bouncing familiars, mimicking familiars, throwable familiars, controlled familiars, and familiars that don't fit into any of the above categories.

Some examples of familiars that generate guppy flies include Brother Bobby, Sister Maggy, Demon Baby, and Li'l Brimstone.

Guppy flies are generated by Guppy's Head

Guppy's Head is a powerful item as it effectively doubles the player's damage output, and when combined with certain other items, such as Hive Mind, can quadruple or even quintuple damage output. Guppy's Head also grants the player the ability to fly, providing a significant boost in offensive and defensive power.

Guppy's Head is considered one of the best items to find in the game, and players will often take risks to enter curse rooms in the hopes of obtaining it. It is part of the Guppy transformation, which requires collecting three cat items, and is considered the most powerful transformation in the game due to the fly generation and flight abilities it provides.

In addition to Guppy's Head, there are other items and familiars that can also generate guppy flies. For example, The Mulligan is a passive item that grants tears a chance to spawn allied blue flies when they hit an enemy. Certain familiars, such as Brother Bobby, Sister Maggy, Demon Baby, and Li'l Brimstone, will also spawn guppy flies whenever their shots connect with an enemy.

Guppy flies are generated by Guppy transformation

Guppy flies do 2x tear damage, so it doesn't really matter if you have a high rate of fire or high damage. Every tear that lands on an enemy and damages it spawns a blue fly that homes in on enemies and does two times the damage as your current damage. With Hive Mind, the flies do 4x damage and spiders do 5x damage.

To transform into Guppy, Isaac must collect three items from the following list: Dead Cat, Guppy's Tail, Guppy's Head, Guppy's Paw, and Guppy's Hair Ball. The latter didn't count towards becoming Guppy in the vanilla game, but does as of the Eternal Edition update.

Guppy flies are generated by Infestation 2

The Guppy transformation is triggered by collecting three of the following items: Guppy's Head, which gives 2-4 flies every room; Jar of Flies, which gives one fly per enemy killed; or Infestation 2.

The Guppy transformation also stacks with the Mulligan item, which grants an infestation shot with a 1/6 chance of spawning blue flies when tears hit an enemy. This means that when Isaac deals damage, there is a chance of a blue fly spawning.

Other items that can generate blue flies include:

• Red Chest: Has a chance to spawn 3 Blue Flies.
• Dark blue champion: Will create 3 Blue Flies when defeated.
• Guppy: Isaac will create Blue Flies whenever his tears or his familiars' tears hit enemies.
• Beelzebub: All enemy flies become Blue Flies.
• Rotten Heart: After clearing a room, a maximum of two Blue Flies spawn for each Rotten Heart in Isaac's life bar.
