===============================
guys i was trying to change the default world of roaming ralph to my own created world… what seems to be the problem?

and guys what is .egg.pz file?

.egg.pz is compressed .egg, you can compress it with pzip and uncompress with punzip, both tools shipped with Panda. This is the most commonly asked question ever here - search the forums or manual.

The roaming ralph world expects there to be somewhere an empty node (or with one vertex) called start_point at the spot where the player is supposed to start.
