Some Skylanders have difficulties do finish the Double Trouble's Heroic Challenge (You Break It, You Buy It!), but there's a way to help. You need any Location Piece (2 will help more)/Anvil Rain, or the Time Twister Hourglass/Winged Boots, or booth. When you go to a place with hard-located enemies for certain Skylanders, use any Location Piece/Anvil Rain to defeat then without breaking anything. Use your Time Twister Hourglass/Winged Boots to gain time in empty sections.
