Movie came out a few days ago (Chip 'n Dale: Rescue Rangers), so a cleanup seems like a good idea. (before more art uploaded)

*** chip_and_dale tag:

1) post #2239871 and post #2239768 : source (artist tweet) does not mention names. Main character has e621 tag of clarice_(disney). Other characters only partially visible, and parent post (post #2239764 ) has only one character tag. Posts already tagged with copyright tag chip_'n_dale. Seems reasonable to remove chip_and_dale tag (from these 2 uploads).

2) post #888997 : already tagged with chip (disney) and dale (disney). Seems reasonable to edit tags from chip_and_dale TO chip_'n_dale.

3) post #882988 : similar to above (ie. already tagged with chip (disney) and dale (disney). Seems reasonable to edit tags from chip_and_dale TO chip_'n_dale.)

4) post #772070 : already tagged with chip (disney). Seems reasonable to edit tags from chip_and_dale TO chip_'n_dale.)

*** chip_(chip_'n_dale_rescue_rangers) tag:
All three posts variants of same art:
post #2893147 * post #2893145 * post #2893143

Not much of male character shown (and this artwork deleted from artist's inkbunny),
but seems reasonable to conclude that male is Chip (based on fur color) wearing his brown bomber jacket (from Rescue Rangers).

So change tag
from chip_(chip_'n_dale_rescue_rangers)
TO chip_(disney) ???

*** footnote:
technically another chip*dale* tag is:
chippendales (106 posts), BUT is unrelated to Disney.
