Tip: A Fantastic chain is a chain of 30+ Tsums. If you happen to have a skill level 6 Rapunzel this mission is super simple; otherwise, try using a Tsum like Eeyore, Chip, Dale, or Daisy and try to use their skill multiple times while clearing as few of "MyTsum" as possible to power up their power until you have enough to make a 30 chain. Another option would be Sully or Alice that create "Big" versions of themselves. Again try to activate their power multiple times until you have enough to create the big chain. Regular Elsa will also work (don't click to clear the "frozen" Tsums after the first time you use her power but instead wait until you can re-use her power and "freeze" a 2nd set, then click to clear them). It is possible Angel and Oswald will work for this also. The 5->4 power up also helps with this mission - See more at: http://www.tsumtsumcentral.com/SC11_TsumTsumMobileGameBingoCard6Missions.aspx#sthash.USCOWzna.dpuf
