Ok so maybe i need a little help

Hey

Im mojo real hojo but really i need help in level 15 im in that long tall tuby place where you find taklits part and i already got nubs part.

The hard part is now where do i go when i am at the place where you whip across and the button is in front of me and i press the button.

The button opens a door from where you can jump to the first of some platforms attached to a central tubular structure. Jump from platform to platform until you're opposite to a blue entrance, then jump into there. The elevator in there is not working yet, so jump across the slot and proceed to another door which opens automatically.
