Why do Slowbros sometimes hold eviolites?

Question

This statistic says that eviolite was the most common item on Slowbro in Generation 5 OU. From what I know, eviolite doesn't boost Slowbro's defenses.

Answer 1

Alright I googled it and was amazed at the first few search results. I didn't expect that it was an actual thing.

Basically the answer is trolls, or people who don't realize Slowbro does not evolve into Slowking.
