Jelly Boy

He can jump and he can launch a large fist from his stomach (he is a blob, after all).

Further, different levels have special power-ups that allow the blob to assume different forms that are useful in specific circumstances.

These include a hot air balloon (for floating up to special items), a hammer (for smashing obstructing blocks), a submarine (for more effectively navigating an undersea bonus level), a skateboard (for blazing through a level on a deadline), and a pogo stick (for extra high jumping).

Not all of the power-ups are useful, though.

One item turns Jelly Boy into a block so that he is unable to move for several seconds.

Jelly Boy collects musical notes in lieu of having a power meter.

Being hit knocks away all of his collected notes and if he gets hit again without having any notes, he will lose a life.

Jelly Boy also collects a variety of fruit throughout his quest.

Accumulate enough fruit to earn extra lives.

Certain types of fruit have other side effects (orange = more time on the clock, avocado = invincibility).

Jelly Boy for Super Nintendo Entertainment System is currently worth €33.77 loose, €151.55 complete in box, and €394.45 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Jelly Boy 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 Jelly Boy, loose is €33.77 and CIB is €151.55 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.
