Claptastic Subconscious map question

On the subconscious map in claptrap dlc , how do you get to the 2 side missions Sum of some fears and a deadlier game? theres also that part of the map also but have no idea how to get there, only side mission i found is the tannis fish mission

You’ll only get these side missions when you advance through the main mission.

when you start seeing green tinted rooms with mc escher stairs start looking for the quests again.
