Forks

I don't have any seeds, but here is a fork.

Forks are items that are seen in Getting Teardrop to Talk.

Coverage
Remote owned one of these forks until Yellow Face stole it to help Gelatin and Puffball make a stack that was shaped like a Sierpinski triangle. Bell swung into the pile, destroying it and sending forks flying. The forks killed Bubble twice and another fork was jabbed into Teardrop, causing her to reflexively bite down in pain (painfully on Ice Cube's) legs. The two forks remained intact after that.

In Why Would You Do This on a Swingset, Gelatin throws forks at the Death P.A.C.T. members, landing on, and killing Pie and Pen. Then Lollipop gives them her fork repellent causing Gelatin's forks to stab Four, and he attacks Gelatin and makes him lose health.

As seen above, Lollipop has a "Fork Repellent", which is a spray can that contains a type of liquid that makes people invulnerable to forks, and reflecting it.

Trivia

 * While one of the forks is from Remote, it is unknown where the rest of the forks collected by Yellow Face are from.
 * The forks are not shaped very much like kitchen forks, but more like pitchforks.
 * One can use a Fork Repellent to avoid getting stabbed by a fork.
 * Bubble, Pie, and Pen have been killed by forks. Pen was not killed directly, but was instead knocked into Black Hole.
 * In Getting Teardrop To Talk, Gelatin make a fork tower, but it is unknown where Gelatin got the forks at.
