I agree with Xavier... Live Ammo would make great plushes.
In contrast to Splat's desires, I've never been a fan of electronic toys.
I think
Kid Robot would do well, except their toys are rarely well-articulated (intentionally). A prime example is the
Gorillaz designer vinyl figures that Kid Robot produced.
The more I think about it, the more I think that
Kaching Brands would be the most fitting for Oddworld. What's most impressive are their
FLCL designer toys (featured below).
Fully articulated 12" Canti...
..and the upcoming 18" Medical Mechanica Robo#5.
These are such an extremely high quality and detail, plus Kaching Brands are not afraid to make them LARGE. I would love to have a collection of the entire Oddworld cast set to scale with one another.
