Tzo Crystal

Tzo Crystals are large crystal clusters that block paths in Skylanders: Spyro's Adventure and Skylanders: Giants. They are found in Molekin Mine, Lava Lakes Railway, and certain Heroic Challenges.

They can be destroyed by Bombs or with these Skylanders:

Trivia

The Tzo Crystals are a reference to the item of the same name in Star Control II, one of Toys for Bob's earlier games.
Diggs refers to the purple crystals in Skylanders: Trap Team's Skyhighlands as Tzo Crystals, although they look significantly different than the Tzo Crystals seen in previous games.
