Frog

Frogs are enemies that appear in several Crash Bandicoot games.

Crash Bandicoot 3: Warped
They are primarily a green color. Frogs are seen in three of the Medieval time levels: (Toad Village, Gee Wiz, and Double Header). The frogs hop around the path that Crash travels, and attack him by hopping towards his direction like obstacles. Crash can usually avoid the frogs by simply dodging them while encountering them. He can also defeat the frogs by his jumping on them, his spinning them away, his slide dashing them away, his body slamming them, hop towards Nitro Crates, or by using the weapon Fruit Bazooka after Coco Bandicoot defeats Doctor N. Gin. If a frog attacks Crash and kills him, instead of turn him into a angel like other enemies, it will grant him a kiss, and afterwards it turns itself into a lab assistant that resembles a prince king.

Crash Bandicoot: The Huge Adventure
These enemies also appear in Crash Bandicoot: The Huge Adventure in two of the sewer levels: (Just Hangin' and Drip, Drip, Drip). If the frogs touch and gets closer to Crash Bandicoot, he turns himself green and falls to the ground like a stone statue just like from Crash Bandicoot 3: Warped in Egyptian levels.

Crash Bandicoot Purple: Ripto's Rampage
In Crash Bandicoot Purple: Ripto's Rampage, a frog from Crash Bandicoot: The Huge Adventure is featured on a trading card.

Crash Tag Team Racing
A giant mechanical frog appears as a background decoration in Crash Tag Team Racing on the Once Upon a Tire track. It wears a crown on its head, referencing the Frog Prince.

Crash: Mind Over Mutant
The frog makes a cameo appearance in Crash: Mind Over Mutant, where it is seen hopping around in the area with Crash and Coco's house and the Doominator ruins. It hops along the lake and can't be interacted with in any way.

Crash Landed
A frog would have appeared in the cancelled game, Crash Landed, acting as part of the Frogzooka weapon but sadly it was cut out of the game.

Trivia

 * The frog kissing Crash and turning into a prince mirrors the Princess and Frog fairy tale, where a princess kisses a frog, who turns out to be a handsome prince after she kisses him.
 * In the second medieval level of Crash Bandicoot 3: Warped, Gee Wiz, there is a frog who will bounce around in a puddle next to a nitro crate. If Crash watches it hop around, it will eventually blow itself up by hopping right into the nitro crate.
