i already have 8 raccoon leafs from adventure. lol. did the quest and sold the rest.

just the south gate and capital sewer adventure everyday for 3 times each using 2 characters

other than raccoon leaf, i also got four leaf clover, light granule, and antenna few times from it

depends on luck i guess as my friend did not get any of those items from adventure but he often get cards every few days. i have not gotten even one card yet from this game.

i open whenever i claim. normally 2 box each time

u must send the required pets to get chest.. like south gate send poring and sewer send a pet with intimacy 5 or above

Not sure on that. I assume it's the success to complete the adventure. I just use the same pets daily. Lvl 40 to 50 pets.

was walking to music box earlier in south gate and saw a weird looking poring. hit it and it was a smokie!! got another raccoon leaf from it. lol
