Shmipper and Smabble

The Mabel and Dipper Lookalikes are two young characters (both male and female) that first appeared in "Tourist Trapped". Their names, birthday, and other information are currently unknown. They are sometimes used as complete opposites of Mabel and Dipper. They have a grandpa who shows his loving affection towards them, a contrast towards Grunkle Stan.

History
In the first scene of "Tourist Trapped", the twins gleefully run around in circles. The Lookalikes appeared in "The Legend of the Gobblewonker", this time with their grandpa. In a fishing boat, the Dipper Lookalike expressed how much he loved grandpa, whom he called "pop-pop". Nearby, Grunkle Stan heard the whole thing, and "booed" the three. That made the grandpa mad, and the Dipper Lookalike mentioned that "maybe he has no one who loves him, poppop," which makes Stan sad.

In Grunkle Stan's flashback of Gideon's tour bus taking the parking spot he was going to use, the lookalikes cheer for Gideon. They also attend a show at the Tent of Telepathy.

In "Double Dipper", the Mabel lookalike is seen at various points in the background of the party, like while Mabel dances and when Pacifica sings. They are both seen in the crowd watching Pacifica, and on a wagon with their family in the intro.

Later on,in Irrational Treasure when the Mabel lookalike is playing on the maypole and trips, Pacifica orders her friends to kick her off.

Both lookalikes attend the Mystery Fair in "The Time Traveler's Pig". The Mabel lookalike also appeared when Dipper trips through the Wax Stan time period.

In "Summerween", the Mabel lookalike goes trick-or-treating, dressed as a daisy, with four other children. Grunkle Stan frightens her off with two other children.

Personality
The Lookalikes seem to be very cheerful, happy-go-lucky, and are usually seen laughing and smiling. They also seem to be quite optimistic and kind (notably in Legend of the Gobblewonker when the Dipper lookalike said that maybe Grunkle Stan had no one who loves him, after he booed their happy grandkid-grandparent moment).

Appearance
The Lookalikes are siblings, and look similar to Mabel and Dipper. They both have brown hair, small noses, and freckles on their cheeks. The Dipper lookalike has blue eyes and is usually seen wearing a red t-shirt; whereas, the Mabel lookalike has green eyes and is usually seen wearing a pink t-shirt. The lookalikes are commonly seen smiling and laughing or acting playfully. They are most likely younger than Mabel and Dipper due to their size.
