Even after all this time, new cheat codes in AoE3 are still being discovered (I certainly can't find any trace of the following on Google).

Forumer Roman2211 has found the following cheats: (Original post)o canada 2005 - Lazerbear
don't kick the pitbull - Learicorn
we <3 fluffy!1! - Fluffy
wuv woo vol.2 - Flying Tapir
wee ooh wee ooh - Andytruck
ding ding ding - Ice Cream
mustard relish and burning oil - HotDog Cart
trade plz - 10k export

All are confirmed working (tested in AoE3+TWC+TAD)
While it has long been possible to summon these in the editor, this is the first time I have seen codes to summon them in game.
This month I have mostly been playing Zelda Breath of the Wild
