I know they spelled container wrong, but that's beside the point. I found this picture on clash of clans wiki and in spite of knowing this was failed logic already, I thought it would be interesting to implement new builder animations. As of now at TH8 the only different builder animation I've seen was with upgrading the barbarian king (and I think it's safe to assume hitting the archer queen with a hammer for several days isn't a factor either).
Animation suggestion list.
Gold mines: Builder enters gold mine and comes out with a cart of rock (as in, making the tunnel longer).
Alternate: Builder enters with TNT then rushes out, showing a small blast of smoke (widening the tunnels)
Elixir collectors: Builder is shown researching different methods of getting more elixir (small blueprints in hand, while looking at different pipes and trying them on)
Barracks: Builder is shown both working on the barracks while also having a small recruitment stand outside the door, where he occasionally sits (meant to look like you're recruiting new troops to your army)
Dark Barracks: Same as barracks, maybe give him a black recruitment stand
Dark elixir: Builder is shown climbing in and out of the elixir hole, being pulled out with buckets of rock (making the hole deeper)
Archer Tower: Builder is shown putting up blocks of wood and hammering them in
Air Defense: Builder is shown with a fireworks contract, buying better fireworks (doesn't look like missiles to me lol..)
Elixir + dark elixir storage's (anything glass related): builder is shown with a bucket of sand which he uses a small torch (with a smelters mask on) to make the domes larger.
Town Hall: Builder is shown with a ladder on the town hall, moving boards/planks/shingles up the ladder working on the roof as well as going down the ladder and using planks on and around the hall (ultimately expanding it)
Army camps: Builder is shown stocking the fire with wood while also waving in a "come on" motion (meant to look like he's trying to get more people to come to the bonfire. which ultimately means a larger army).
Laboratory: Builder comes in a white scientist suit and works with chemistry sets and large chunks of metal trying to build his laboratory (kinda like Dexter's laboratory [Old cartoon show])
Spell Factory: Builder is shown working with a wizard trying to create more spells (or a witch)
Cannons: Builder is shown contracting heavier cannonballs while smelting pieces of metal together on the cannon itself.
Tesla Towers: Builder is shown with small metallic strands, placing them in the right spot to expand and generate more electricity.
Bombs: show builder testing out different bombs and gunpowder's to increase blast power.
Giant Bombs: Same as small bombs, but bigger.
Seeking air mine/bombs: Show builder releasing balloons in the air with dummy bombs strapped to them.
Mortars: Builder is shown smelting pieces of metal to the mortar.
Clan Castle: Builder is shown laying stone bricks to expand the clan castle.
Skeleton Traps: Builder is shown working with a witch in order for him to learn how to spawn more skeletons.
(could have the coffins open and see more skeletons inside as it levels up)
Gold Storage: Builder is shown placing boards & hammering in place to expand the storage)
X-Bow: Builder is shown working with an archer trying to get better string for the bow, while also working with small black chunks of metal to make it bigger (could also show them working with different bolts)
Inferno Tower: Builder is shown with a ladder, moving small chunks of metal up and down the tower (while smelting them into place). Could also do something with fire/magma on this one.
I think that covers just about everything. Hopefully some of these features could be implemented. Post suggestions for different animations below as I'm fully aware some of these are generic and I came up with some right on the spot.
