You should receive a special title as a reward for completing all of the lobby parkour courses, atleast I think. Maybe something along the lines of 'Parkour Pro' would sound pretty cool. Besides, there's no rewards as of right now so I think it would be something neat.
If you didn't know already there's one in every game lobby excluding clans.
There was a super tough one for me, it was tucked into a wall almost near micro battles. I never would have found it if it wasn't for someone else.
Also there's one on top of one of the seaweed looking things surrounding the map
And I think there's like atleast 1/2 per house
Another one is hidden between 4 blocks near gladiators, well disguised
And another one is on a tree trunk near the fireplace
other than that it's just loads of searching
