Every Rillaboom card

2 printings across 1 expansion. Evolves from Thwackey.

The short version

Rillaboom has two printings in Pokémon TCG Pocket, all of them in Mega Rising. It is a Stage 2 Grass-type Pokémon with 150 HP, weak to Fire, with a retreat cost of 3. They run to two rarities — one Rare and one Art Rare. The hardest to pull is the Art Rare from Mega Rising, at about 1 in 186 packs, or 400 Pack Points to buy outright. Nine hunts in ten end inside 427 packs, which is about 7 months at the two free packs a day the game gives you. The printings come out of the Mega Altaria pack. The most recent is Rillaboom #027, from an expansion that shipped in October 2025. That printing carries the ability Captivating Rhythm: Once during your turn, you may flip a coin. If heads, switch in 1 of your opponent's Benched Pokémon to the Active Spot. It attacks with Drum Rush, which costs three Grass and one Colorless energy and hits for 120. The card’s own words: “The one with the best drumming techniques becomes the boss of the troop. It has a gentle disposition and values harmony among its group.” It has been drawn by two artists.
