This article is a list of Tennis Ball's inventions. It is sorted in chronological order.
Weak Trembling Fortress[]
- Main article: Weak Trembling Fortress
The Weak Trembling Fortress (WTF) is the currently employed elimination area for BFDIA. It was built by Tennis Ball in Team No-Name during "Intruder Alert". It is built with wood planks and nails, with a sign saying "Weak Trembling Fortress" in the front.
In "Well, Look Who It Is!", the contestants who had been eliminated during or after the events of "Intruder Alert" up till that point (including Yellow Face, whose elimination was the same episode) escaped the chamber, thus all former inhabitants are currently free.
Appearance[]
It's a poorly made shelter made out of wooden planks and nails. It has a sign with its name on the front of the shelter near the roof. There are massive holes along the walls of the shelter, making it not very useful to keep contestants inside its walls. Over time, more and more planks fall off it, making planks and nails scatter on the grass outside.
Satellite[]
The satellite was created to deflect paint shots, it ultimately failed.
Laser Pointer[]
The Laser Pointer was made in "Catch These Hands" in order to alert Golf Ball to the challenge.
Microscope[]
The Microscope was made in "Taste the Sweetness" out of headphones and Fries's car to analyze the Yoylite.
Trebuchet[]
Tennis Ball enjoys Trebuchets, greatly discussing them often and building one in "Insectophobe's Nightmare 4".
Oil Rig[]
The Oil Rig was made to easily fill the jetpack on Donut's island in "PointyPointyPointy ♫".
Raft[]
The Raft was made to progress from Match's island in "PointyPointyPointy ♫".
Super Stick Shoes So Ha![]
Super Stick Shoes So Ha! is a project made by Tennis Ball used to cross the loop-de-loop from the Goiky Canal Highway in "Well, Look Who It Is!", meanwhile Tennis Ball refurbished the Non-Slip Shoes So Ha to the Super Stick Shoes So Ha!, Golf Ball got partial credit since it was refurbished in Golf Ball's Underground Factory.
Growth Ray[]
Growth Ray is an item in Battle for Dream Island Again. It is currently owned by Tennis Ball and was created by him in the episode "Spore Day".
Appearance[]
The Growth Ray is a cylindrical shooting device with a handle and a scope for aiming on one end. On the Growth Ray are 3 circles with varying sizes, seemingly to indicate which end the ray would come out of.
Creation[]
Tennis Ball put a water droplet with a shrunken Nickel, finding what chemicals made him grow. He used it to create the growth ray.
Nickel's trinket detector[]
Nickel's trinket detector Was first seen in "Respect to the Wicked". Tennis Ball uses it to find Nickel's trinket, which is 1 meter away. Later, Pencil uses it to take down the pile of dirt so that she could touch the W.O.A.H. Bunch trinket.
Bike[]

Normal

CGI
The Bike was made in "Start the Shift". Tennis Ball used it so that he could recover everyone from the HPRC. Unfortunately, the bike crashed when it lands on Yoyleland.
Yoylite Time Machine[]
The Time Machine was made in BFDIA 17 to remove the cake from his fuzz. Tennis Ball combines the energy of both the Yoylite and the regenerative properties Noctiluca yoylean algae to create it. Later, Nickel and Tennis Ball fall on the Yoylite, causing them to get transported into the future. This invention continues to get used until they are transported to TPOT 13, where the Yoylite gets struck by lightning, causing the invention to break.
Grotatoes[]
Grotatoes were made sometime before "Welcome Back" to emulate potatoes being able to grow in less sunlight, they were made to keep Fries alive inside of Yoyle City.

The TV upgrade originally discussed in "Balancing P.A.C.T" was created in "Category One" to distract the Giant David.
