Need Help with Custom reading book animation.

[Thobeo]

Good day guys!
I'm working on another personal character mod for my friend, and that character can summon a follower.
I used the template of Yakuzashi on this post: 

And it's work just fine now.
P/s: Thanks for the tutorial, it's very nice!

Now what I want is to change the current summoning animation - which is "reading book fx" - to something else, cause I want my mod character to use different kind of item to summon her pal.
Hope someone can give a hint how to do that.

Thanks for reading the post!

By the way,
I noticed when the character read book to summon follower, there is a line "only_use_by_wickkerbottom".
It'll be great if I can change that line to something the character would say.
