As mentioned on the child post, this is a parody of the intro to "Golden Youga Gekijou" or "Golden Western Theater" - a Japanese TV program that ran from 1971-2001. If you're a Sayonara Zetsubou Sensei fan, you might recognize it from there since they parody it as well in one of the episodes.
Meiling or Meiling&Sakuya Remilia or Remilia&Flandre Cirno or Aya Reimu&Donation Box or Nitori&Big Dog EX Keine or Suika Reisen or Tewi Spaceship or a crab claw? The Yakumos or The Moriyas Mokou&Kaguya or Tenshi&Iku
The only scene that doesn't seem to vary is the one with Alice and Marisa.
