On the other hand, an evidently particularly lazy and both uninspired and uninspiring design would be Woobat. It is a puff ball with a coofy expression, chibi wings, and a fat nose with a heart stamped on it. It is bad insofar as it is virtually nothing---as if a child not yet in school had drawn it.
Joltik has a similar problem. It is a puffball with small stubby limbs and beady eyes. One gets the impression of wool, with its highly cartoony attempt at the bristles of a tarantula. There is nothing to it other than moe-bait---it lacks so much detail that it completely undermines its own concept.
Now I don't need to mention how unpopular Swoobat is; Galvantula on the other hand has received a lot of positive attention at least from Gen V fans. And yet it suffers the same fundamental issue of lack of detail in the artstyle as its preevo. Not only does its bristles still look like wool or harmless fur, with not a single strand or differentiation in the mass to be seen, not only do its limbs still favor cuteness over utility or, again, detail, but there is absolutely nothing about its design that suggests its typing or functionality other than its color. It is in a word, totally amateur and very nearly a throwaway design.
Well now there's an often overlooked mon I think actually displays a modicum of creativity among the whole dex, and that is Vullaby. It is for the most part a dull vulture/condor chick, also noticeably lacking in real detail, though not to the same extent as the aforementioned. But, its saving grace is its diaper, further emphasizing the baby theming (which not even Johto and Hoenn babymons pulled off [excepting Elekid], though Sinnoh's did)---which is in fact a skull. And unlike being hack-ishly slapped onto it randomly, the heart incorporated onto this skull diaper is actually the skull's nasal cavity. All in all, an interesting concept with an ultimately dull design.
