G3 Rainbowberry with my rendition of what rainbowberries look like as they were never shown in the G3 movies. Her card's info says:
HOFS-EN030:
My Little Pony Rainbowberry
LIGHT / Pony / Level 4 / ATK 1600 / DEF 1200
"Rainbowberry Season" cannot be destroyed by card effects. Once per turn: You can put 1 Rainbowberry Counter on all monsters on the field. "My Little Pony" monsters gain 300 ATK for each Rainbowberry Counter on them, also destroy any non-"My Little Pony" monster with a Rainbowberry Counter(s) on it.
