Original Description:

In Colin’s words:

“Our heroes, Sonic, Pibby, Mordecai, SpongeBob, and Twilight Sparkle along with the rest of the Mane 6, are battling other cartoon heroes that have been corrupted by the Glitch. The heroes are fighting for their lives to save the multiverse, but the three most powerful and dangerous corrupted, Huggy Wuggy, Mommy Long Legs, and Boxy Boo from the horror game Poppy Playtime, are going to be a real challenge for our heroes. All the characters in this story are stronger and more powerful than the original characters, which makes for some really big battles. Also, our long-time beloved characters, like Bugs Bunny and Tom from Tom and Jerry will appear in the story. Hit the “Watch” button to see the epic crossover story unfold.”
