Make - Dependency building different than explicit build

I have a rule in my makefile:

$(OW_GROUP_ONE_C): $(OW_GROUP_ONE_PNG)
for file in $^; \
do \`enter code here`
        grit $$file -ftc -fh\! -fa -gt -gz\! -gB4 -m\! -p -pzl -pu16 -o $@; \
done

It builds a single c file out of different images, those are iterated in a for loop (They are, I checked using an echo)

The rule which depends on that is

$(OW_GROUP_ONE_O): $(OW_GROUP_ONE_C)
$(CC) $(CFLAGS) -c -o $@ $<

which is executed via

$(SPRITES_BINARY): $(NORMAL_PAL_OBJ) $(SHINY_PAL_OBJ) $(SPRITE_FRONT_OBJ) $(SPRITE_BACK_OBJ) $(NORMAL_CASTFORM_PAL_OBJ) $(SHINY_CASTFORM_PAL_OBJ) $(CASTFORM_FRONT_OBJ) $(CASTFORM_BACK_OBJ) $(OW_GROUP_ONE_O)

If I execute the rule by calling "make $(OW_GROUP_ONE_C)" everything works fine, but as soon as the rule is executed via dependency from another rule, the loop seems to just read the first file. I again used echo to check, but the loop accumulates all files in the list. I don't know what the deal i, the tool (GRIT - GBA raster image transmogrifier) should be able to handle that, but there must be a difference between calling the rule explicit if it works that way...

Thanks in advance for any hints!
