11 Points (“Because top 10 lists are for cowards”) has compiled a list of the most egregious rip-offs–and a few genius additions. Meet Naughty Bubble and Big Spinach (in Harry Potter and the Chinese Porcelain Doll). Follow Harry as he says goodbye to Hogwarts and transfers to “Asia’s top wizardry school, Qroutes School of Witchcraft and Wizardry” (in Harry Potter and the Half-Blooded Relative Prince). Go under the sea in search of a waterproof pearl (in, um, Harry Potter and the Waterproof Pearl).
The full list is here.–David E
