A scrundle basically means a jumbled group of objects. Similar to scrundled, scrundingled, or any other variation you can think of.
I use it as-
Scrundle- a jumble of things
Scrundled- mixed up/ messy, Can also be used in a situation where, in a Looney Tunes cartoon, a character would have stars circling around their head, or any funny mess up, such as tripping and falling on something small, but not getting hurt.
Scrundingled- Messed up, jumbled, etc. Similar to Scrundled but more fancy. The two are pretty much interchangeable.
"Come check out this dragon's Scrundle of treasure!"
"John Scrundled my puzzle, and now I have to start over!"
"I got Scrundingled by that piece of ice which made me tumble through the snow!"
