Jelly

A jelly is used as a boost to help Croc in both Croc: Legend of the Gobbos and Croc 2. They can be used to bounce on in order to reach normally unreachable areas or items, but cannot be eaten. Their functions are different in each game:

Croc: Legend of the Gobbos
In the first game, they are depicted as pink and are featured in many of the levels. Croc may simply jump on them to advance higher in the air.

Croc 2
In the second game, they are also used to bounce higher, but can only be purchased by Swap Meet Pete in his shop. As with most shop items, the maximum number of each type of jelly is 9. They can be placed only onto jelly placeholders which will then enable Croc to bounce on the jelly. If Croc uses a jelly which doesn't give enough of a boost, i.e. using an Orange jelly on a Red jelly placeholder, he will not be able to reach what was supposed to be reached with the correct jelly, and will have to exit the level in order to correctly use that particular jelly. It also works vice versa, as Red jellies can be used on Orange jelly placeholders, for example, but this is considered to be a waste of crystals/Red jellies.
