The Dink Network

I think you should first add these graphics to you graphics folder.
Then start modifying your Dink.ini to add the graphics.
I.E. :

add in Dink.ini a line like this:
load_sequence_now graphics\monster\walk1- 851

This should be the first sequence for walking of your monster.
Then continue adding sequences:
load_sequence_now graphics\monster\walk2- 853
load_sequence_now graphics\monster\walk3- 855
load_sequence_now graphics\monster\walk4- 857

If your monster has any attacking sequences, place them like this:
load_sequence_now graphics\monster\atk1- 861
.
.
.
and so on. You should place the sequences like this because remember that this monster has its base_walk and its base_attack.
Well, I think that's it to add the graphics, but I think there you should edit its hardbox and depth doth in DE.

Hope this helps

EDIT
the sequences are divided into frames.
I.E. the walk1 sequence is divided at the graphics into frames:
walk1-1 (first frame), walk1-2 (second frame), walk1-3 (third frame) and so on.
But the lines at Dink.ini are written just in the whole sequence:
load_sequence_now graphics\monster\walk1- (insert sequence here)
