This situation happened to me recently, but while we were playing we let it go as the card stated. Octillery's Suction Cups state: As long as Octillery is you active pokemon, whenever the defending pokemon retreats,discard all energy cards attached to the defending pokemon when it goes to the bench. (allow me to use Wailord ex for THIS example, just to make it obvious) Anyways, If the defending pokemon is a Wailord ex with only 2 energies, can it retreat if Octillery is my active? I know a pokemon can't retreat unless it fulfills the retreat cost, but octillery makes it pretty clear they only have to discard the energy cards attached. So my question is, would it REALLY be able to retreat?
