How did people manage to do this? I never figured it out on my own.

if you jump up and drop cubi they float in mid air
if you jump up and battle cubi- they float in midair AND stay for an extended period of time without being stolen

Thank you! And how do you get into an area like here? You walk over this bridge but not under it. And under the stairs in Guillermo Gamera Way?

That is more complicated, you had to have someone follow you, lag them out so that you could leave and return to a street before they loaded, (thus causing them to be in two streets at once) then follow them- their path would often take you under the intended walking space.

Wow. Thank you again. That is definitely more complicated than I ever would have thought.
