fire spin - if the enemy pokemon die while is effected by fire spin next pokemon that come in battle still trapped (effect can be lost only by death of fire spin user or after 4-5 turns) (TESTED)

 

whirpool - i guess the same bug exist with that move too (not tested yet)

 

Whirpool vs Gastrodon (Storm Drain) - Move not damage gastro and raise his sp atk but stil trap it and lose hp every turn. (TESTED)

 

 

 

also something more i dont know if is bug or not is non damage grass moves vs sap sipper is just immune dont raise attack (no idea if this is bug or not)

Hey SiTzei. After testing whirlpool in showdown to be sure this is how it should go :

1st turn whirlpool will raise gastrodon's sp.attack by 1 stage as any other water move would do in a storm drain poke. Since storm drain make gastrodon immune to water attacks though, whirlpool should not have any other effect . Neither making gastrodon losing hp each turn and increasing its sp.attack every turn nor preventing it from switching. Basically the move fails in 1st round and just increase gastrodon's sp.atack by 1. So yes since you tested it , i guess whirpool and storm drain interaction is bugged.

 

Regarding fire spin , yes the effect should end once the pokemon faints , or if it use rapid spin.

 

About the sap sipper ability : . Any kind of move that ''hits'' a sap sipper pokemon increases its attack by 1 stage and has no effect ( this includes moves like spore , stun spore . leech seed and not only direct-damage grass moves). That said , moves like aromatotherapy or synthesis that have nothing to do with the oponent sap sipper pokemon , will not activate the ability and won't fail.

 

Hope that helped and have fun :Angel:
