## Playing Entei's Pokédex cry can distort Raikou's and Suicune's
([Video](https://www.youtube.com/watch?v=z305e4sIO24))
The exact cause is unknown, but a workaround exists for `DexEntryScreen_MenuActionJumptable.Cry` in [engine/pokedex.asm](engine/pokedex.asm):
```asm
.Cry: ; 40340
call Pokedex_GetSelectedMon
ld a, [wd265]
call GetCryIndex
ld e, c
ld d, b
call PlayCryHeader

**Workaround:**
```asm

ld a, [CurPartySpecies]
call PlayCry

```
## Lock-On and Mind Reader don't always bypass Fly and Dig
This bug affects Attract, Curse, Foresight, Mean Look, Mimic, Nightmare, Spider Web, Transform, and stat-lowering effects of moves like String Shot or Bubble during the semi-invulnerable turn of Fly or Dig.
