Penta Penguin was also seen in the boss fight against Dingodile in the game Crash Bandicoot 3: Warped, though it was originally unconfirmed that that was actually Penta and not another penguin. His return in the Crash Bandicoot N. Sane Trilogy remaster of Warped implies that he was indeed the penguin that appeared in the original version of the game.
Penta is later seen in Crash Team Racing, where he is an unlockable character via a secret button combination in the main menu. Aside from the N. Sane Trilogy, this is the only game where the name Penta appears. He also appears in Dansu! De Jump! Na Daibouken.
Crash Bandicoot 3: Warped
As described above, Penta appears in the boss fight with Dingodile. He is threatened to end up burnt by Dingodile. However, when Crash is warped there, Dingodile's attention is turned away from Penta and he runs away. Later, after Dingodile is defeated, he comes and jumps triumphantly on Dingodile's body.
Crash Team Racing
This is Penta's second appearance, and the first where his name is revealed. He is only unlockable via cheat code. If players hold down R1 and L1 and press down, right, triangle, down, left, triangle, and up, at the main menu, he will become a playable character. In CTR's PAL and NTSC-J versions, he is the only racer with maxed out stats, the same as Nitros Oxide. In the NTSC-U version of the game, Penta has the same stats as Polar and Pura, and he is good at turning but doesn't have much speed. His appearance looks a bit different from the other games; in Crash Team Racing, he is black, he has a scarf, his eyes are closer together, and his beak is smaller.
Penta reprises the same role he has in "Warped"; running away from Dingodile before the fight and coming back afterwards only to jump on him.
Penta makes an appearance in Dansu! De Jump! Na Daibouken. He tends to be very greedy since most of the time he's a merchant selling items for high prices. He has a girlfriend named Gurin and is head over heels for her and will do anything to win her affections. He is later seen in another chapter selling jet packs when Crash and Cortex decided to go into space to find the Power Stones much faster.
Penta's name might be a pun on the phrase "pent-up", the definition of which means "repressed or suppressed, especially of emotions or impulses". This is plausible because he is suppressed in the game unless players know the super button combination.
Penta also means "Five" in the Greek language.
Penta is one of the only three characters players cannot race against as a computer controlled character (apart from Fake Crash and technically N. Tropy as he is only computer controlled in Time Trial mode as a ghost).
In the NTSC version of CTR, Penta's data is largely unfinished. Examples of this include him being protected by Aku Aku, but having Uka Uka show up in the item box. Also, as well as penguin noises, the sounds he usually makes, Penta also makes various statements which are actually unrecorded lines. For example, sometimes when boosting, Penta will say "Penguin Yay One" or "Penguin Yay Two."
Penta is the only secret character to have Aku Aku as a mask during a power up.
Penta's victory theme is the same as Ripper Roo and Papu Papu.
Out of all of the characters that appear in CTR (other than the masks and Fake Crash), Penta is the only one who does not have a text entry in the closing credits.
Penta is also the only character to have different statistics in CTR. In the NTSC-U version of the game, he has the same stats as Polar and Pura. However, in the PAL an NTSC-J version, he has the same statistics as N. Oxide.
The beta version for CTR claims that Penta became a weather forecaster, and kept predicting another Ice Age.
Penta makes an appearance in the CTR intro, when Polar appears (behind him), though, he's hard to spot as he's very small.
