Riolu Hatch Day returns on April 18 from 11 a.m. to 5 p.m., and Riolu will hatch far more frequently from 2 km Eggs during the six-hour event. Trainers also get an increased chance of hatching Riolu’s Shiny form, along with 2× Candy and 2× XP from hatching Eggs and 1/2 Egg Hatch Distance.
The event also pushes more 2 km Eggs into PokéStops, giving players more chances to line up hatches while the bonus window is open. A $1.99 ticket adds Premium Timed Research, Star Piece, Super Incubators and 1/4 Egg Hatch Distance, while free Research offers one Incubator and 5,000 XP.
For players trying to plan the month, Riolu Hatch Day lands inside a packed April stretch that also includes Sustainability Week 2026 through April 20. That event debuts Silicobra and Sandaconda and raises shiny odds for Pokémon such as Lapras and Togetic, before the following week swings from hatching to heavy combat.
The contrast is the point: April 18 is built for walking, incubating and chasing Riolu, but the calendar around it does not stay soft for long. A separate $4.99 ticket later adds bonus XP, Max Particles and a Max Mushroom for extra battle damage, making the end of the month a quick turn from egg-focused play to battles that reward a very different kind of preparation.
