Ok i have come up with a theory of what the plot for Rainbow Rocks is. What if Dashie in the EG world takes up being in a band? then in some way the pony dash gets her cutie mark changed to drums! then twi has to return to the EG world and stop the EG rainbow dash from being in a band! and they have to kill the human discord with the power of rock
This one is quite obvious. Hasbro is a corporation, after all. They're only in it to turn a profit. The MLP franchise is only growing in popularity, and FiM has already been confirmed for a fifth season. Also, "coz" is a slang word that means "cousin." There is no other definition of the word. GRAMMER NAZI ATTACK!!! I'm assuming that by "pissed" you mean "drunk," and not "angry." This theory is possible, but seems very unlikely. "Crappy" is a subjective term. Many thought that the first EqG movie was crappy. Many more enjoyed it. Until you actually watch the movie, you can't say whether or not it has relevance to the show or makes sense. Your theories are based entirely on assumption and personal bias.
