Level bugs

Mushroom Hill Zone

Act 2 boss sometimes shows as Eggman rather than Eggrobo

KnucklesAgainstRobotnikInMHZ2.png

Sometimes, Knuckles' boss will have the face of Dr. Eggman rather than Eggrobo as it should. This usually happens after the player loses a life, because it's caused by the game's not having sufficient time during reloading to patch-in Eggrobo's face over Eggman's

Not fixed in any version.

Flying Battery Zone

Knuckles fights Eggman instead of Eggrobo

While playing as Knuckles in Flying Battery Zone's second Act, the Hang Mobile is piloted by Dr. Eggman instead of Eggrobo. Unlike the above bug, this occurs every time.

This is likely to be due to the game's artists missing this sprite. The battle's perspective is different – the Eggpod and therefore its pilot face the screen head on – and thus requires new animations, which the artists did not implement for Eggrobo.

Not fixed in any version.

Lava Reef Zone

Exploding Iwamodoki shows 100 points but does not award them

The badnik Iwamodoki releases a small animal and displays a "100" points score when it explodes, but it does not award points to the player. Perhaps the lack of points – but, of course not the presence of the score notification – is intentional because the player cannot be directly responsible for destroying the badnik, which instead self-destructs when a character approaches. This might indicate that Iwamodoki was supposed to behave like Asteron, which upon self-destructing neither awards points, displays a notification, nor releases an animal.

Not fixed in any version.
