Cookie Run: Crumble — Blueberry Bird (C Support)

Blueberry Bird is a C-rarity Water-element Support Cookie in CookieRun: Crumble. Their skill Blueberry Bird Wish Delivery runs on a 6.25-second cooldown and sends birds to restore HP to low-HP allies and increase DEF.

What Blueberry Bird Wish Delivery does

Two effects in one skill. The birds heal allies who are low on HP, and they increase DEF. That is a more complete Support package than the skill text makes it sound: a heal that goes to whoever is hurt, plus a mitigation buff that reduces how much healing the next wave will need.

The targeting detail matters. The skill restores HP to low-HP allies, not to everyone. On a full-health team the heal portion does little, so the value of the skill swings with how much punishment you are taking. In easy content it is close to a DEF buff with a wasted half; in content that is actually hurting you, both halves fire.

At 6.25 seconds it cycles reasonably often for a Support. The two other Support Cookies that appear in Blueberry Bird’s data run 6.5 seconds (Herb) and 8.0 seconds (Cheesecake), so it is not slow for its class.

Per-stat values are not published for C-rarity Cookies in the sources we use. We have stat templates for the SSR classes only, and we do not guess at the rest. Treat Blueberry Bird’s raw numbers as unknown rather than assuming they scale down from something else.

Volley: three Cookies grant it

Blueberry Bird receives Volley Synergy and grants nothing. Here is every Cookie in the launch roster that can supply it:

Herb Cookie is the best pairing, on cooldown alone — 6.5 seconds against 8.0 and 10.0. A shorter cooldown means the provider re-triggers more often, so the same Synergy coming from a faster Cookie is simply worth more.

The one worth flagging for a new account is Cheesecake Cookie, which is R rarity. It is the cheapest source of Volley in the game and it is only 1.5 seconds slower than the SR option. This is the pattern that repeats across the roster: the Synergy a Cookie wants is almost never gated behind rarity, and a cheap Cookie usually covers it well enough that you never need to chase the expensive provider. Blueberry Bird is a C-rarity Cookie whose Synergy an R-rarity Cookie supplies, so the whole pairing costs you very little.

There is a second reason to keep a Volley provider regardless of Blueberry Bird: Ion Cookie Robot, an SSR Tank, also receives Volley from these same three Cookies. A Cheesecake or Herb you level early does not go to waste when Blueberry Bird eventually leaves the team. Full provider tables are on the Synergy page.

Note the class spread. Two of the three providers are Supports. If you run Herb or Cheesecake to enable Blueberry Bird, you are spending two slots on Supports, which is a real cost. Tiger Lily Cookie is the only Charge-class provider, and it is also the slowest at 10.0 seconds.

It grants no Synergy of its own

Only 18 of the 69 launch Cookies grant a Synergy at all. Blueberry Bird is not one of them — its list of granted Synergies is empty.

This is the most important fact for planning around it. A Cookie that grants a Synergy has a claim on a permanent team slot even at low rarity, because something else on the team is built around receiving it. Blueberry Bird has no such claim. Nothing depends on it. When you bench it, nothing else on your team gets worse.

Competition

Our roster data lists no other C-rarity Support Cookie, so Blueberry Bird has no same-rarity classmate to be measured against. That sounds flattering and is not: the comparison that decides its fate is not with C-rarity Supports, it is with every Support above it.

Blueberry Bird’s cooldown is competitive with both. What it does not have is their rarity, and rarity buys stat ceilings and promotion headroom that a cooldown number does not show. A C-rarity Cookie with a good cooldown is still a C-rarity Cookie. Assume you will replace it, and be pleasantly surprised if you do not.

Team fit

Water element: extra damage to Fire, extra taken from Grass. See the element chart.

As a Support it wants a frontline ahead of it, and its heal-the-hurt targeting means it works best behind a Tank that is genuinely absorbing hits, rather than on a team that either wins clean or dies instantly. Neither of those extremes gives the heal anything to do.

If you are already running Herb or Cheesecake for Ion Cookie Robot, adding Blueberry Bird costs nothing extra in Synergy planning — the provider is on the team already.

Should you build it?

Early on, yes. Long term, no. It is a working healer plus DEF buff on a decent cooldown, available at the lowest rarity in the game, and its Synergy is covered by an R-rarity Cookie. For the stretch of the game where you are short on Supports entirely, that is enough.

Replace it as soon as you have a higher-rarity Support worth investing in. The usual reason to keep a low-rarity Cookie permanently — that it grants a Synergy nothing else on your roster can supply — does not apply here, because Blueberry Bird grants nothing.

Do not spend scarce promotion materials on it. Spend them on the Volley provider instead; that investment keeps paying after Blueberry Bird is off the team.
