SKT/VGtM: Alternate Giant Abilities

I've a hunch the location is painfully obvious; regardless, it's driving me crazy.

Where in the SKT module and/or Volo's Guide to Monsters is the catalogue of alternate Giant abilities? For example, the Fling ability. I scrolled through the module journal entries and Volo's but I can't find anything detailing these abilities. I know the campaign book provides an appendix; I just can't find it in the module. Does Volo's actually include this or am I imagining content? It's not terribly important (my players are chapters away from fighting Giants), but I wanted to use the alternate abilities as inspiration (and templates) for "novel" actions for other monsters. I did find an index of these abilities using Google. Is the appendix/index included in the module and/or Volo's?

Thanks!

I don't own either of these on Roll20, so I can't answer your question directly.

Looking in the books, I can't find them in Volo's, but they are in Appendix C of SKT under the heading "New Giant Options."
