Help with animated (multi frame) sprite and move sprites / timing issues and background "redraw"?

[RestlessRabbits]

Hi everyone,
I tried adding a few sprites as objects to the clockface, which worked fine so far.
3 things I am still trying to achieve:

1. Objects that "overlap" with the jumping character are partially overdrawn by the background of the character.
   For this I either try to add a "function" as a color, that saves the old pixel and restores it after animation or either redraw all objetcs and the background once the jump is done.

2. Add a stationary animated sprite.
   For this I still need to figure out how to handle the frames. Anyone made approaches here already? I was thinking about having a coin sprite rotating like it does in newer dame versions.

3. Move a sprite along the top lika a banner with a message above the clock
   For this I need to figure out the frame/timing handling as well. And the redraw of pixels passed that belonged to a sationary object like a cloud.

Did anyonealready tried something similar and may point me some directions?
Replacing and placing new sprite is no issue so far, besides the background handling.

If I make some progress I of course will share what I got so far.

I added this to the wrong repository - sorry. The approaches I try to figure are related to https://github.com/jnthas/mariobros-clock
Any ideas from folks fiddling around with something similar still really appreciated.
