Although the dramatic size discrepancy between these two pokemon makes it impossible in nature, and when it is done it is typically the product of mad scientists, it is indeed possible to breed Skitty and Wailord via artificial insemination. When the Wailord is the female, an apparently ordinary Wailmer is produced, no more strange or remarkable than any other crossbreeds. However, when the Skitty is the female, the resultant pokemon is no ordinary Skitty. Although when it hatches its egg is no larger than the rest of its species, the Skitty will grow at a tremendous rate until it reaches the size of its father; these half-breed Skitty, not Steelix, are the largest land pokemon to ever walk the earth.
The sheer size of large pokemon alone makes even gentle and lazy giants like Snorlax dangerous, and for a creature with Skitty's playful, feline mannerisms, size makes them destruction on four legs. Their habit of chasing their tail, adorable in an ordinary Skitty, is deadly to people and buildings alike when the tail in question is heavier than a wrecking ball; the pins can still be shot out as weapons, but they are less needles now than swords. Likewise, their tendency to chase moving objects becomes a method of hunting everything from Donphan to cyclists. A single Skitty can lay waste to a city more easily than Groudon or the megafauna of the Cenozoic ever could.
Tragically, Skitty are the furthest thing in the world from a malicious pokemon. The moment they finish their chase and realize what they destroyed, they scamper away into the forest, hoping it will have enough food to sustain them, and never show their faces to humans again.
Reviewers, if you want to ask a question, please do so when signed in. That way I can respond directly with the review reply feature, and I do. With regard to the reviewer who asked me, Nosepass not moving is stated in its Sapphire pokedex entry. (And it makes sense. Those legs are too short to go anywhere.)
