Adventures in Wonderland (1992)

S1E59 The Grape Juice of Wrath

The White Rabbit accidentally spills grape juice on the Queen's throne and rallies the other inhabitants of Wonderland to assist him in cleaning it up before the Queen comes back from her day of blueberry picking. Unfortunately, their attempts to fix the stain are comically ineffective. In the end, Rabbit gathers the courage to confess to the Queen about the mishap, only to discover that she is unfazed by the incident, as she had intended to have the throne reupholstered regardless.
