Perhaps it could be done in a similar way as the narration text is done in SMI. For instance, the large text narrating the "meanwhile" after you leave the Scumm Bar for the first time and the first cinematic with LeChuck appears. Make it that style of large narration text instead of Guybrush speaking it. The text could work in larger amounts that way.
"Booyah! Look out, LeChuck! Here comes Guybrush Threepwood's glowing sword of hot monkey vengeance!"
-Guybrush Threepwood, Tales of Monkey Island
