A California family whose son was diagnosed with leukemia is thankful for volunteers who spent the week at their home in order to give one special little boy a big surprise.

"Special Spaces of San Francisco partnered with Disney On Ice performers this week to transform the small bedroom Austin Bolender shares with his brother into a place fit for a king — a Lion King, which is one of Austin's favorite movies."

A large mouse named "Mickey" was there for the big room reveal.

Diagnosed in May, 2014, Austin has undergone several chemo treatments and will undergo a complete bone marrow transplant on February 9th at UCSF Benioff Children's Hospital.
