Winter Wrap Up (event)

Since natural processes in Equestria are regulated by ponies (except in the Everfree Forest), all seasons need to be changed manually. The Winter Wrap Up is the annual activity of clearing winter and bringing in spring.

In cities such as Canterlot, magic is used to end winter. However, Ponyville was started by earth ponies, who did not have access to such magic. Thus, the process of changing the seasons required the collective effort of the entire population. It became a bonding event, so even after unicorns started settling there, the tradition of using only manual labor to change the seasons has continued.

Action as complex as changing the season requires exceptional organization. All ponies are assigned to one of three teams: weather, plant and animal. In the latest Winter Wrap Up, everyone was wearing a vest with the color of the team.

Weather team

 * Leader: Rainbow Dash
 * Jacket: blue

Composed mostly of pegasi, the weather team clears the sky of clouds and lets the sun warm up the land. Assigned ponies depart to retrieve the birds that have flown south for the winter. Several earth ponies, Pinkie Pie being one of them, are assigned as lake scorers. They cut ice with their skates so it will break more easily when the sun comes out.

Plant team

 * Leader: Applejack
 * Jacket: green

Earth ponies from the plant team ensure that Ponyville will have enough food during the year. They move snow off the fields, plow them, and plant and water the seeds.

Animal team

 * Leader: Sparkler (fan name)
 * Jacket: tan

The animal team mostly consists of unicorns, but ponies from other races, most notably Fluttershy, are seen on the team. The team wakes up hibernating animals, cleans up their dens, and ensures that they have food to eat. Returning birds need nests to lay their eggs, so Rarity was put in charge of making them.

Organization

 * Leader: Mayor / Twilight Sparkle

In the namesake episode, the traditional methods had failed for the past few years for unspecified reasons. Arguments arose and inevitable mistakes turned into major problems due to a lack of planning and coordination. Twilight Sparkle lent her skills to the effort, helping Ponyville bring spring in on time, earning the title of All Team Organizer.
