Why are the munchkins glad Dorothy came to munchkinland?

The Munchkins are glad Dorothy came to Munchkinland because her arrival signifies the end of the Wicked Witch of the East's reign of terror, which had oppressed them for years. Dorothy's accidental house landing on the witch not only frees them from her tyranny but also transforms her into a symbol of hope and liberation. Additionally, they celebrate her as a hero, expressing their gratitude and joy through song and dance, marking a newfound sense of freedom in their lives.
