Ganjlek in Plane of Knowledge will only give you one magic dust, asking for another has the text "Here you go, Happy frost fell". You do not receive another dust.
Just say 'more dust' to Ginjleg Gigglegibber this is a very well thought out walk thru so you hit all the steps and you won't have to do it twice. http://www.bonzz.com/frostfellnewyear.htm#yeti
I only completed it once. I got one dust. Using the walk thru in the link I posted you can ask for the second dust. That works fine and I then had 2 dusts in my inventory. Which is also what dev told us would work Naylie; I believe what you are looking for is "more dust". ~~~~~~~~~~~ You say, 'Hail, Ganjleg Gigglegibber' Ganjleg Gigglegibber says, '[Happy Frostfell] Naylie. I am happy to report that the dolls have been delivered to their proud [new owners].' You say, 'You know who else is a proud new owner? Belumb! Do you think I could have some more?' Ganjleg Gigglegibber says, 'What you want [more dust]?' You say, 'Yes, I would like more dust to make more dolls.' Ganjleg Gigglegibber says, 'Great! Here you go. Always happy to help spread the joyous spirit.' You say, 'Yes, I would like more dust to make more dolls.' Ganjleg Gigglegibber says, 'Great! Here you go. Always happy to help spread the joyous spirit.' You say, 'Yes, I would like more dust to make more dolls.' Ganjleg Gigglegibber says, 'Great! Here you go. Always happy to help spread the joyous spirit.' ~~~~~~~~~~~
