Stimpy is a lovable yet dumb cat. He his [sic] Ren's loyal best friend and sidekick, and is always ready to teach you how to be happy?
You wanna teach me how to be happy? I'll teach your grandmother to suck eggs! [Okay, okay, calm down, Burl Ives --ed.] You'd have to be an eediot to release a Ren without also releasing a Stimpy, and Loyal Subjects isn't. At least not in that regard - they still did the thing where a bunch of the boxes for the toys are blacked out for absolutely no reason, and the printed casepack ratios don't match up with either reality or basic mathematics, so some things never change.
In most fiction, it's the cats who are smart and the dogs who are dumb, 
but Ren & Stimpy inverted that. Of course, you may forget Stimpy is supposed to be a cat if he's not actively doing something feline, like coughing up hairballs or pooping in a box of sand. He's a big, potato-shaped lump with a face that takes up half his body and a nose that takes up most of his face. The sculpt is decent, if a little off-model from the cartoons (though at least some of that can be laid at the feet of Action Vinyls' brand of stylization). He's got a big smile and his tongue is hanging out of his mouth, but the fact that the eyes are painted looking upward feels like a mistake. The red of his body is lighter than it ever was on the show, too.
Since Stimpy is so large, he doesn't have any accessories. He does, however, have decent articulation: balljointed hips and shoulders, and swivel wrists and ankles.
Considering how much The Loyal Subjects loves releasing variations of their Action Vinyls, it's weird the only one in this line was a Golden Stimpy which, unless it was based on the Marvel comic, comes from nowhere; why not take a cue from Palisades and make them Fire Dogs? As something other than an SDCC exclsuive, that is. There was also a "Naked Stimpy" exclusive to Hot Topic.
Ren & Stimpy was a victim of its own success. Despite constantly running over-budget and behind schedule (the pilot episode aired twice because the second episode wasn't ready yet), it was a smash hit and inspired any number of imitators, most of whom are forgotten today - if you say you fondly remember Schnookums and Meat, you're lying - but it was so influential and such a darling that the crew got swelled heads about their own talent, culminating in a letter sent to the studio executives saying episodes would "cost what they cost and take as long as they take" - a "my way or the highway" ultimatum that backfired when at least one high-level creator was promptly shown to the nearest metaphorical highway, and told to take his studio with him.
The show's impact on the animation industry can't be ignored though, despite its short original run (and the utter failure that was the 2003 attempt to revive it). Loyal Subjects' Nickelodeon Action Vinyls line included not only Ren & Stimpy, but also Rugrats, Wild Thornberrys, Hey Arnold, Spongebob, CatDog, and more, but Ren and Stimpy were the big draws for me. The toys themselves are fine, though they definitely have room for improvement; it's just nice to be able to get a set of the boys that doesn't cost 47 meellion dollars.
