This Marill was available to be befriended in the Dream World Isle called the Pleasant Forest.
The gender of the Marill is variable, meaning players may befriend a male or female variant.
Depending on the player's score on the mini-game, the last slot of Marill's moves may contain its basic move Defense Curl,
or special moves either Aqua Jet or Ice Punch.
Pleasant Forest was available by default from the opening of the Dream World September 18, 2010,
till the closing of Dream World January 14, 2014.
However if the player already has the Marill in their Entree Forest uncaptured,
the date of capture can literally be any date.
(Additionally, the NDS date system could have been changed to any date anyway)
