The Mean, Nasty, Horrible Hats

The Mean Nasty Horrible Hats are a trio of brothers and antagonists of The Sidemen and are JJ and Deji's younger maternal cousins and Yinka's nephews. They debuted in series 8 episode 44 Sidemen Meets the Mean, Nasty, Horrible Hats and have made several appearances so far. The three are mostly seen wearing distinctive hats with bandana paisley patterns on them, which is a representation of the nickname.
They are the sons of Tiwalade and Romoluwa Oketke, JJ's maternal aunt. The three were born and raised in Watford, London. The Oketke family lived next door to the Olatunji's and would visit daily until according JJ, moved down to Eastbourne in 2016 where they stopped seeing each other. However they still kept in contact and would speak on a daily basis on the phone. 
The three are usually mean, cruel and spiteful who cause trouble for everyone they come into contact with, but are sternly scolded by their parents, aunts or any other form of authority when they are found out. They are also known to bully and prank the Sidemen and smaller animals and sometimes, their reckless actions can cause serious consequences either for others or themselves. Despite being unruly, obnoxious and obstreperous at times with dangerous stunts, they aren't inherently evil and have a good, caring side (the three showed genuine remorse for their bullying antics after getting chased and attacked by a Lion), and do mean well.
In later episodes, their bullying antics seem to have died down, but they are still reckless and troublesome. The three brothers deeply care for each other, even if they argue from time-to-time.
