Stickman Skyblock Parkour

The identical red and blue stickmen with their twin sisters' faces want to cross the finish line and enter the portal there. Please lend them a hand and guide them to the entrance. Be careful as you make your way down the cliff and into the water because you can't swim. Make sure that both of your siblings make it to the entrance of the portal without getting hurt. Allow both of your brothers to enter the portal so that you can proceed to the next level.
