This search engine surely is extremely useful, but not that fun... Wouldn't it be great to kill time there too, just like on google? Here's some stuff I was thinking of:
-Duck rush (kinda like zerg rush but with ducks attacking instead)
-Duckhunt (and an annoying dog like this one: https://duckduckgo.com/?q=doge&iax=1&ia=...
-A long time ago in a pond far far away? Maybe? (A long time ago in a galaxy far far away alternative)
-Do a backflip (Do a barrel roll alternative)
