Well to answer your question on the Seven Sirens, the Coral Siren represents Envy because she's the one that looks mostly human and probably has to use that giant mech to equal the strength of the other sirens. Lobster represents Lust because her role in the game suggests that she has an admiration for Shantae.
Yo Chimera. I was wondering if it would be better to use this new template I create for pages like http://shantae.wikia.com/wiki/Shantae%27s_mother or if it's better to make an infobox with that Shantae image and something like "No Official Image Available" above it.
I admit I'm quite impressed with all the maintenance work you've done, so thank you and welcome again on the wiki! I have to say I'm not sure I understand all of your edits, especially on the template thingies which are not my field, but be assured we're grateful for the time you spent on all this work.
