OK, she is a very well-known LB. Can be nice, but also very unpredictable. She was reported several years ago to have slapped a customer in a bar. Circulates between bars: when she is kicked out from one bar for bad behavior, she goes into another. Is very sexy. If she is in a good mood and she likes you, she can be fantastic. If not, she can be a pain in the ass. Was also reported to cause considerable damage to the hotel room equipment when she disliked the customer upon some (minor) disagreement.
I saw her last May in Chily bar, Nana Plaza. Did not see her there en of October. Try all Nana Plaza LB bars, ask for small Cartoon. Several BMs on this forum have her phone number, too. Not me. I always considered her as too dangerous.
Caveat: There is also a tall Cartoon. That is another LB, different from Cartoon you are looking for. Tall Cartoon works in Casanova.
