How the Grinch Stole Christmas! (TV special) Seuss cartoon, "Horton Hears a Who"). Both story collections contain selected dialogue and music numbers. The "isolated music tracks" in this edition are taken directly from the television soundtrack and are not the re-recorded tracks from earlier versions. The dialogues are the originals, being voiced by Boris Karloff for "Grinch" and Hans Conried for "Horton." Because Thurl Ravenscroft was not credited in the closing credits of the 1966 television special as singing the song "You're a Mean One, Mr. Grinch", it is sometimes attributed to Boris Karloff. After becoming aware of this oversight, Seuss himself called Ravenscroft and apologized profusely
How the Grinch Stole Christmas! (TV special) does not depend on material things. The Grinch begins to understand the true meaning of Christmas, though he barely does so in time to prevent the stolen treats from going over the cliff and while he tries to stop the sleigh from falling off, his heart grows three sizes—granting him "the strength of ten Grinches, plus two!", which he needs to lift up the sleigh. He brings everything back to the Whos and participates in the holiday feast. He is given the honor of carving the roast beast, while Max gets the first slice for himself for all his troubles.
