Don't try using Thinner on them, as you will only make them explode faster. If you are near a Spladoosh when they are growing, they will explode and you will lose about two to three lives. To avoid this, keep a safe distance away while using Thinner. And be warned - You'll need a full bar.
If you quickly walk away, there is a chance they will go back to sleep.
If you use Paint, they will become your friend and go back to sleep. If they are growing and they become your friend, they will shrink back to their normal size and go back to sleep. They may explode when agitated when they are your friend, but that rarely happens.
If you use a TV in front of them, it will distract them. They'll lean forward and laugh occasionally. If you use a TV on top of them, this will electrocute them. Hitting them with anything (Paint, Thinner, Spin attack) will break out of the TV trance though and will either explode in the usual fashion or continue watching if you've painted them.
Use an Anvil on a Spladoosh and it will explode instantly.
If the Spladoosh is painted and you do a spin attack, you will just bounce off the Spladoosh's fat layers, but you will not receive damage from it.
A befriended Spladoosh can revert back to an enemy again after two hits from a miss-target from a Beetleworx or a large Blotling like a Slobber. For example, say a Basher accidentally hits a Spladoosh instead of Mickey. It will lose some Paint. If hit a second time, it will lose all the paint and will revert back to being an enemy.
An early concept art shows a Spladoosh standing (below), which in the game they're always asleep.
Befriended Spladooshes are the only Blotlings, when befriended, that cannot help you in battle with enemies, mostly due to not being able to walk and being inactive for long periods of time.
Although Gus said Spladooshes don't move around, one managed to lock up Gremlin Neville in a cage in the Lonely Manor approach.
The Spladoosh is the only Blotling to not have red eyes in Epic Mickey during harder levels.
The "z"s that come from them while they sleep are the same font as the toy story logo.
