Fruit Gushers are hexagonal-shaped candies that frequently appear in Homestuck. They are first referenced as bearing a resemblance to Build Grist.Then John Egbert receives a box of Gushers as a birthday present from his Dad, and has a fondness for the sugary snack until having a mild mental breakdown upon realizing that the manufacturer of Fruit Gushers is the "loathsome batterwitch" Betty Crocker. Jane has a similar breakdown, but for the reverse reasoning: she loves Crockercorp but despises gushers. She , and on the same page insinuated that they may be made from wiggler slime.
In the Homestuck universe, Gushers come in such flavors as Wild Cherry Apeshit Apocalypse, Ranch Dressing Rampage, Cool Fructose Monsoon, Kiwi Mango Colonic Rush, Mixed Berry Social Anxiety Disorder, Wicked Watermelon Groin Injury, Jammin Sour Diabetic Coma, Sour Grape Electric Holocaust, and Neon Green Ecto-Facial Blast, as well as the pictured Massive Tropical Brain Hemorrhage, though it is possible that some of these are made up by John during his mental breakdown.
Betty Crocker Barbasol Bomb
The Betty Crocker Barbasol Bomb is a black and white-striped Gusher with both Betty Crocker and Barbasol logos. John creates it by combining a box of Fruit Gushers he found in his Dad's Room with a can of shaving cream. The resulting bizarre Gusher costs 1 unit of Shale and 1 unit of Build Grist. Evidently, its contents and apparently fragile nature necessitate a "Handle with Care" mantra. It is a combat item that causes a destructive explosion of foam/Gusher filling.
In the Act 4 , the Betty Crocker Barbasol Bomb will go off in a blast of shaving cream if it is expelled from the Sylladex. However, it does absolutely nothing to the Imps. John later tries to use the bomb to put out the fires ravaging a Salamander village. However, as it turns out, shaving cream proves to not be an ideal fire suppressant.
Hellacious Blue Phlegm Aneurysm Gushers
John creates the Hellacious Blue Phlegm Aneurysm Gushers by combining Fruit Gushers with some of the blue ecto slime Nannasprite leaves on his bedroom wall. The item costs 24 units of Build Grist, 30 Shale, and 18 mercury. These Gushers evidently have ghostly healing properties, as evidenced in Act 4's when John uses them at low health.
Bodacious Black Liquid Sorrow Gushers
Rose comes up with the Bodacious Black Liquid Sorrow Gushers by alchemizing the Ink of Squid Pro Quo with John's Hellacious Blue Phlegm Aneurysm Gushers. They cost a mere 1000 tar. Along with giving the box a dark makeover, the ink reverses the healing properties of the Gushers, making them pure poison.
