Even though the games are solemn, freaky affairs, they do have their moments...

* Try persistently failing the StalkingMission in Four Islands some time.
--> "Let's be faster."
--> "Are you really Ecco the dolphin? Let's try again."
--> "So many times... I forget how many times..."
--> (After ten failures) "[[MercyMode Ecco, here is the song you need to get past the stones. Good luck.]]"
* The Clan grunts in ''Defender'' occasionally show some DeadpanSnarker tendencies.
--> "First they tell us to turn it[[note]](the Hanging Waters Generator)[[/note]] off. Then they tell us to turn it on. They should make up their minds!"
* Requires some guts on the part of the player, but try making the great white shark angry and then tail-walking around the surface in ''Defender''. He'll just swim around in circles, unable to grab you (well, most of the time - occasionally he'll get lucky).
* The tubes in the Hanging Waters levels can be used, in some spots, to launch Ecco into the mountainside at high speed.
