Wimp Out causes the bearer to switch out (or flee in a wild battle) when its HP falls below 50%.
-Wimpod stats according to its PokeDex page.
Golisipod is definitely a hard Pokemon to train. Wimpod's ability means that you can't lower its health when catching it, and its catch rate is pretty low, so it can be a difficult Pokemon to acquire. This is the least of problems, however. Wimpod has horrible stats, and while it as above average growth rate, it will doubtfully kill many opponents, and you will have to rely on Exp. Share a lot. Finally, Wimp Out and Emergency exit as their abilities isn't the most fun.
Is it worth it? If you want to get through the game quickly, I would say no. Golisopod is actually pretty powerful, with high attack and defense. First Impression attempts to make up for its pitiful speed stat. However, it just takes way too long to get, and Golisopod's stats aren't even that exclellent. Despite priority in First Impression and Aqua Jet, Golisipod's low speed stat is noticeable, and for in-game, you don't want your Pokemon to be so slow. But most of all, Emergency Exit is going to be a huge pain. While it is rather bulky, it isn't uncommon for its health to fall below 50%, causing it to switch out, and, since it usually slower, not be able to attack.
However, it isn't the worst, and if you are willing to commit some time into training, than you should consider using it. Many people simply use it because it has such a great design. It also simply destroys wild Pokemon. Just be careful with its ability, and it shouldn't be too bad.
