The sweetened cereal, made of oats, consisted of animal-shaped pieces similar to animal crackers.
Television commercials featured a cartoon lion, Linus the Lionhearted, voiced by Sheldon Leonard, with the slogan "The one and only cereal that comes in the shape of animals,"[1] sung to the tune of "Trepak" from Tchaikovsky's The Nutcracker ballet.
[2] This time, the commercials featured a puppet mascot named "Crispy" with pom-pom antennae, a pom-pom tail and a furry yellow body, resembling a moose.
Crispy used an impersonation of Jimmy Durante including the nonsense phrase "Ah-cha-cha-cha".
Together, these puppets spoke the cereal's tagline: "It's indubitably delicious."
