Ok, I beat the game, and I am having trouble finding that old lady before finding Connie. Where is she? I found everyone but her and she is the only one that's keeping me between Connie and the battle with her. someone help.
like people say,
Mrs. Echinacea ... Nefro-Nefro Town. Next door neighbor to Connie's old house...
I look there and she isn't there. What am i doing wrong?!
i talk to everybody, and see those who i need to see, but ZIP, nothing!!!

Found this if it helps


Marjoram - In Garland. He's in the food shop next to the Lobster Inn.

Fennel - He's inside the ballroom of Station Hotel in Garland, which is across the street from the Riverside hotel.

Rosemary - In Eurydika. Coriander's mother is in the house where you last left her. If you were Bloody Mantis and skipped the quest, this is the town where you go to kidnap Coriander and wipe Basil's nose across his butt in trot battle.

Dr Nutmeg - At Vision Ranch. Fight his trot garage while there. If you fight it already, you will not have to undergo this fight again.

Basil - In Nefroburg. The Four-Eyed Loser is north of the station, in one of the tunnels leading to the industrial yard. Ginger is there in the daytime. Basil will direct you to the next door neighbour.

Echinacea - In Nefroburg. The next door neighbor to Connie's old house will only appear if the above people are found and talked to.

After all these people are talked to (not necessarily in order), you find Coriander at Seagull Beach. Challenge Coriander to a fight once you find her, or you will not unlock her trot in the trot battle mode (the extra mode on the main menu). If you miss challenging Coriander to a trot fight in "Year After" mode, you can keep playing. Reload an earlier game before finding Coriander (but finished the game), do the sidequest (fight her) and save that game to a different slot. Coriander will be unlocked in trot battle.

Finally, if you take Coriander back to Eurydika, she will visit her mother. If you feel like travelling solo, tough luck. You cannot leave without Coriander if you board your trot.
