===Effect of Unown===
Using TM17 will trigger ACE from address $FA47 onward, an echo RAM copy of $DA47, in the middle of Unown's stat values. Lvl 5 Unown will never have stat values that can cause the game to softlock or crash, allowing execution to safely slide through this region until it encounters Quagsire's data.
===Effect of Quagsire===
Translating the species ID, held item ID and first move ID of Quagsire's data to assembly results in the following code:
<pre>
C3 AD D8 jp $D8AD ; 5 bytes before the start of wBoxNames
</pre>
This causes a redirection of execution to a region right in front of wBoxNames. This region is mostly unused and consists of $00 values, with the exception of $D8AF which describes the current active box. After safely sliding through this region, the box name code is executed.
===Effect of the box name===
Box name data starts from $D8B2 onward. Converting the provided mail code to assembly results in the following:
<pre>
AF xor a ; a = $00
3D dec a ; a = $FF
EA 8B D5 ld ($D58B), a ; Address corresponds to TM27's quantity
C9 ret ; Return to normal game operation.
</pre>
