That area currently contains a few Despicable Me themed food and merchandise locations.
And speaking of Despicable Me Minion Mayhem, the new Secret Life of Pets attraction will make its home right next door to its fellow Illumination property, between it and the Minion themed Super Silly Fun Land play area.
I reached out to Universal Studios Hollywood and have confirmed that the new attraction won’t require the closure of any of the existing locations, even temporarily.
