Pelican Opener

The Pelican Opener is like Albatross; a single bag opener that results in a platform T-Spin Double and is usually followed by a T-Spin Triple. In case of an S piece start it is always executable, if J piece shows up before L and O. In order to finish the T-Spin Triple in the second bag, the O, I, S and L pieces must be placed like shown in the fifth diagram.



Third Bag and derivations
There is a nice continuation, if the T-Spin Triple is finished in the second bag. In this case the third bag's pieces can be be placed in a way that results in a T-Spin Double followed by a chance for a Perfect Clear after 3 further lines (after 10 cleared lines in total, 20.48% chance).



If Perfect Clear is not possible, one may set up a T-Spin Double.

If O comes before L, Perfect Clear after 10 lines is still possible (13.6% chance). If Perfect Clear is not possible, one can make a T-Spin Triple in one of the two following ways. 5-bag Perfect Clear after the TST is a possible follow-up.

Perfect Clear from the first loading method (32 solutions, 98.10% chance):

Perfect Clear from the second loading method (one solution, 20.32% chance):

Riviclia's Pelican
One can go for a Perfect Clear after 14 lines with this continuation. In the second bag, L needs to come before S and T before Z. In the third bag, the J, S, Z and O can be placed in one of the three following ways. In the fourth bag, LJO can be placed in one of the two following ways. Finally, a Perfect Clear is always possible in the fifth bag. All minimal solutions are shown. This setup is invented by a Korean player Riviclia.

STSD Followup
This continuation creates a donation STSD after the Pelican's 1st T-Spin, which may lead into a T-Spin Triple and a T-spin Mini Single or a C-Spin. It requires an S before Z and T (Z before S and T if flipped) to be buildable, otherwise, other continuations should be built instead. This continuation has been discovered by Luden.

Z (S if flipped) should always be stacked on the side to fill in the T-spin.

Depending on your next pieces, you may be able to build a T-Spin Triple into a T-Spin Mini Single. Here's a few exemples, but feel free to build by yourself due to next pieces rng.

Early L / J

I wall

C-Spin Variation
Instead of a T-Spin Mini Single, one could attempt for a C-Spin by placing L,J and S (Z flipped) on the side to create one and by filling up the opposite side.
