Buy Adopt Me Ibis
The Ibis is a pet in Adopt Me. Once it is full grown, it can be used to make a Neon Ibis. From there, it can go one step further and become a Mega Neon Ibis.
Neon pets are made in the Neon Cave, which sits under the main bridge. To make a Neon Ibis, you need 4 full-grown Ibis. All four are combined into one Neon Ibis.
A Mega Neon Ibis takes more pets. You need 4 full-grown Neon Ibis to make one. Since each Neon uses 4 Ibis, a Mega Neon Ibis uses 16 Ibis in total.
Fly and ride abilities can carry over. If just one of the pets you combine is a fly pet, the new pet can fly. If one is a ride pet, the new pet can be ridden. You do not need all four pets to have the ability.
An Adopt Me Ibis is the first step toward these upgrades. Collect enough of them, and you can build your way up to a Neon or Mega Neon Ibis.
