Weekly challenges are a feature of Pikmin Bloom, introduced in version 44.0. Each week, a certain challenge (such as walking some number of steps) is set for all players, and players can work together with up to 4 friends to complete the challenge as a group. Completing a challenge before the deadline gives rewards to each player in the group.
To begin a weekly challenge a player needs to open the activity list menu and select a challenge. A menu displaying groups participating in the selected challenge will be presented. These groups are comprised of the player's friends, as well as their friends. If there are no such acquaintances participating in challenges prior to the player opening this menu, or if all groups are filled, the player will be presented with the option to begin a new group.
While a challenge is active its display in the activity list changes to display the challenge's progress and its participants. Tapping on the challenge will bring the player to a screen displaying all participants jogging together, each alongside a few of the Pikmin in their active squad. This screen features various elements, such as the step total and step goal, how many days remain to achieve it, the date the group began the challenge, a breakdown of each player's contribution towards the goal, alongside their profile images and names, as well as a random quote.
Upon completing a challenge, whether by reaching either the goal or the expiration date, the player is brought to a screen displaying the group and their progress. A star-rating from 1-3 is awarded based on how much of the goal was achieved. Each player's Mii will then take turns jogging to the fore, as their contributions are displayed and celebrated by the the other Miis and Pikmin in the group.
Types of challenges
There are currently 2 kinds of weekly challenges, and more will be added in the future. Challenges of different types can be done at the same time, but challenges of the same type cannot be done at the same time.
These challenge players to walk some number of steps in the week.
Flower planting challenges
These challenge players to plant some number of flowers in the week. When one player in the team plants 1000 flowers, other players in the team get a small number of petals as a reward. In the screen where participants are shown walking, decorative flowers of different types appear on the ground.
List of weekly challenges
The table below contains information on each weekly challenge that has happened so far. With the exception of the first challenge, weekly challenges go from Monday to Sunday. The rewards listed are the rewards for completing the challenge and getting a 3-star rating; not completing the challenge and getting a lower star rating will give rewards with lower amounts of the same nectar types. All players in the challenge are given the same rewards. Nectar rewards ignore the regular nectar storage limit, so they can cause the amount of nectar a player has to exceed its normal maximum value.
