I can't do 3rd job

I can't talk to Door of Dimension

 

As a thief, you need to go to the door of dimesion located at monkey swamp 2

 

Where is monkey swamp II ?

 

Its located at Kerning. Head towards the Swamp of Despair (The portal near the kpq). Continue to the next few portals till u reach Dangerous Croko 2. There is a hidden portal at the top which leads to Monkey Swamp.
