It ' s painted black , has multiple pointy parts , and holes . Also overpriced . Seriously , it ' s just a dumb marketing term . Some knives are better suited for military or police work than others , but the individual needs and tastes of the people using them in those roles means that a very large variety of knives are employed . They are usually just regular knives that happen to suit the user . <| sep |> ok well then maybe it ' s because I don ' t try to escape often enough . because I don ' t give up that fast . <| sep |> not sarcrastic , i hate this guys voice , the language is patrinizing , it ' s simplifying things too much . mainstream philosophy my ass . <| sep |> Okay , so let me help clear up some misconceptions you ' re having on the Happiness thing and then see if I can offer a solution to your problem . First off , the TM Trick doesn ' t actually work . I myself did the trick for a solid 20 minutes using a timer app on my phone to make sure I did it exactly 20 minutes and it didn ' t work . Another user tried it for a solid 3 hours and it didn ' t work . The TM Trick was a coincedence in which several people were very close to evolving their Pichu , Munchlax or another Pokemon that evolves via happiness , tried spamming TM ' s back and forth for a while before using a Rare Candy Which gives quite a bit of happiness when fed to a Pokemon , and their Pokemon just happened to evolve . Walking with the Pokemon in the first slot of your party doesn ' t actually affect the happiness like it used to . Walking with the Pokemon in your party DOES give it some happiness , but it ' s not nearly as much as you might think . Battling with the Pokemon can help , but if it faints , even if you use a Revive , the Happiness goes down . The best way to gain happiness from battle with a Pokemon that isn ' t quite on par with the rest of your team , or one that keeps fainting when you try to attack with it Either because it ' s slower than the opponent or the opponent just hits really hard is to have it in the first slot and then immediately switch it with another Pokemon . Doing so will allow it to get the I was in battle ! bonus happiness and a little extra EXP , while keeping it from accidentally fainting . Now , the solution to your problem would likely be a combination of things . The first and foremost would be to go into Festival Plaza and find your Friendship Cafe . You might need to spend some time here to get some FC Festival Coins , but when you have around 50 , you can buy the the happiness booster meals from the Cafe for your Riolu . The most expensive one gives the most Happiness , the least expensive gives the least . If you do that for 2 days and then use the battle strategy that I suggested , then finish it off with a Rare Candy , you should be good .
