Son Son

The screen features six continuous platforms that occasionally feature small gaps.

Sonson and Tonton walk automatically across these platforms.

Pressing up or down will cause them to jump up or down to the next platform.

Pressing left causes them to move more slowly than the screen scrolls, essentially continuing to move forward but at a reduced pace.

Pressing right does the opposite - SonSon and TonTon will move across the platforms faster than the screen scrolls.

The duo have only one attack - the ability to fire energy blasts from their stalves.

Touching an enemy or an unfriendly projectile causes the player to lose a life.

If a player has any additional lives, they will return to the screen riding on a cloud that will give them temporary invincibility.

If the player presses the control stick in any direction, the cloud will disappear and the character will resume its usual walking mode.

The cloud will eventually disappear on its own if the control stick is not used.

Power-ups come in the form of various fruits which produce points (with enough points giving the player an extra life).

Gathering certain fruit will cause all enemies currently on a screen to turn into point-bearing fruits.

Walking across certain platforms will randomly cause a bamboo shoot to sprout, yielding many extra points.

It is possible to play the game co-operatively with partner who plays as TonTon (who is Zhu Wuneng in the original story).

Son Son for Nintendo Entertainment System is currently worth €18.70 loose, €53.29 complete in box, and €170.96 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Son Son has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Son Son, loose is €18.70 and CIB is €53.29 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
