Mostly very old/outdated extensions and one-offs posted in the TurboWarp Discord server.
Most of the extensions here should not be used in actual projects.
Extendable Blocks 2 but with the original concept of having palette buttons to extend/retract blocks, making it a bit more usable. Alt title: Poor Man's Extendable Blocks
The snapshot stage block from Looks Plus, but it captures the current state of the stage instead of the one from last frame.
(JOKE EXTENSION)
Basically, custom reporters before custom reporters existed.
(One-off) A block that enables dragged C blocks wrapping around blocks. Is essentially a prototype for a Scratch Addons addon.
(One-off) Disable or enable specific sprites running scripts.
(One-off) Toggle the touching blocks being able to sense the camera feed (normally disabled for privacy reasons).
(Historical) An older version of Inline Blocks.
(Historical) The old version of Images. Also sometimes called Unsandboxed Images.
(Historical) An extension of join blocks, inspired by a concept for kccuber's MeowBlocks mod. So old that it existed before unsandboxed extensions. Fixed so that it actually works.
(Historical) TurboWarp Blocks but as a userscript that could be loaded in E羊icques (pre-unsandboxed extensions). Thumbnail also from E羊icques.
(Useless) A test for argument-dependent menus (ADMs). No practical use.
(Useless) An example on how to make custom extension C blocks, posted in the TurboWarp Discord.
