- Tank is the only main dinosaur that does not defeat any of the Spectral Space Pirates' altered dinosaurs.
- When she fights the D-Team, she is often defeated by Ace using Ninja Attack.
- Tank is highly skilled at digging tunnels very quickly (both horizontally and even vertically), and is capable of creating smooth, circular tunnels in spite of having spikes on her back.

- Tank can be accessed on the DS Game by putting a specific code on the Stone Circle after defeating Dr. Z with his Tyrannosaurus, Mapusaurus and Saurophaganax.
