Saw the room and added it to the owners list on the wiki. Thanks :-)
Was it originally like how it was in this
Youtube video? With no icon and it having the same name and description as the normal one? I wonder why they would intend to give out a slightly different Green Parasol. A white one would have been a much more appealing gift!
Also when they came out do you remember these Parasols being quite common at the time? Because I believe there were slightly similar credit campaigns going on at roughly the same time across most hotels, and the Rares obtained from them are considerably more common now compared to the Zon.
Though maybe the amount given out was limited in a similar way the
Aqua Slurpee was during the 7-Eleven campaign. How that worked was users had to redeem a Habbo prepaid card bought from a 7-Eleven and hope they were one of 7 daily winners of the machine. This seems feasible but there are probably over 10 times more Aqua Slurpees than there are Zons, so they could have made it more unlikely to win a Parasol from redeeming a prepaid card - which would explain why so few are around now. Does this sound vaguely familiar to you?
I guess it would be fitting for them to release a Parasol during the summer :P
