However, unlike when catching regular fish or other items, the random value used to determine whether a River Jelly is successfully caught is predetermined. This value only changes when catching a [[Cave Jelly|Cave]], River, or [[Sea Jelly]], or any [[Fish]]. It is not changed by catching Algae, Trash, or any other catchable items.<ref name="jelly_RNG"/> Because of this, after catching Trash using the Training Rod, it is necessary to catch a regular fish before another River Jelly. This can easily be done by switching to any [[Fishing Pole]] other than the Training Rod, continuing to fish until an actual fish is caught, and switching back to the Training Rod.

Ordinarily, 10% of possible random values result in a successful River Jelly catch. Each level of [[Luck#Luck Buffs|Luck Buff]] increases the chance of a successful catch by 5%.<ref name="jelly_rate"/> So with +8 Luck, 50% of random values will result in a successful catch. This allows for longer streaks without failing a Sea Jelly catch, although the player will still unavoidably catch some Snake Skulls.

It is also possible to achieve similar rates when fishing in either [[The Desert|Desert]] pond, although either [[Green Algae]] or [[Pyramid Decal]] instead of Snake Skulls will be the alternative drop. Fishing in the Desert does not require use of the Training Rod if done after 8 pm or in the lower pond, as there are no fish to be caught. However, this also means that there is no convenient way to refresh the Jelly's random value once it changes to a failing value.
