Umm...No you have to be almost done with lvl.5 like (When you finish a mission you will go level 6 BUT! Rewind that mission and you can jump BTW it takes 2 days to jump because as soon as u become a sr u barely get missions but Thomas Moorland gives u a mission to "The Council Man" then u earn REPUTAION WITH SILVERGLADE THEN do a couple of missions till ur nearly done will lvl.5 and then u can JUMP!!!!!!!!!!!!!!!!! )
As many quests have been added after the game was released, the jumping quest has been pushed forward, meaning that you'll get it later than you would have gotten it in the game's early days. Almost none of the quests are 'fixed' to a level, so you can't really know when you get them. Just be patient - you'll get it soom enough!
Patience is a very important trait when you're playing Star Stable!
You do not get the jumping quest when you turn a certain level. You must be far enough into story quests that you recieve a quest from Justin Moorland, who will be at Steve's Farm near Silverglade Village. The quest is called "An Obstacle to Build" which comes after you help Harold the baker get some flour from Barney.
