"Dolphin up" What the hell is that? :- :P
It depends on how you want to get onto it,
One way you could do is either wheelie, or (sort of) manuel the front wheel on top of the 'object', then push the bars forwards and de-weight the back wheel.
Or you could try backwheeling it...
Start off a bit far back off the object with you "good foot, chocolate foot" etc, back, then do a half crank rotation and as your good foot comes forwards, pedal kick and push the bars upwards, and tuck.
You wont always get backwheeling first time, it takes alot of practise, just keep trying and you'll soon get it.
