Sometimes I have to remember KISS (Keep It Simple, Stupid).

The "landslides bury" animation is very simple.  But it works for me!  It took nearly no time at all to create.  I'm really getting the hang of Scratch!

I want the animations to play one at a time, so I need them to wait until it's their turn to display.  It is easier to created the animations as separate Scratch projects, then import them into the final one.  That way, I don't have to watch the whole animation to work on each phrase.  After importing them into a single Scratch project, I set 'waits' and 'hides' so that they display and run in the right order. 

Scratch is very logical and there good 'Help' on every command.  Just right click on a command to see it!
