Hollow Bat guide
Hollow Bat is a Mythic earning $80K/s, and the figure is identical to Orca from the Abyss Ocean. Within the Halloween Dimension it ranks 25th of 29, and among the 32 Mythics it is 23rd, well under the $220K/s median. Terrorbird, from the Skeletal Egg, is the next one up at $110K/s.
The wiki lists it under the shared Halloween Dimension Egg, with a grow time of about 10 seconds and an $8M hatch reward, about 100 seconds of its income. The same egg also covers Candy Corn, Scarecrow, Pumpkin Golem and Soul Phantom, so hatching one is a lottery across very different pets.
That spread matters. The same egg that gives you a Hollow Bat can give you Soul Phantom, an Eternal at $2.5B/s. If the Bat is what you get, Silver brings it to about $96K/s, Golden to $200K/s and Rainbow to $280K/s. A Rainbow Hollow Bat would pass the median Mythic, which is a decent consolation for a low pull.
