Analysis
Computed from our dataset — recalculated on every build, so it stays true as the data changes.
Who this can buff
Jingle Deer's effects name Light and Tank. That matters because a targeted buff only pays out on cookies that match: 12 of the 71 cookies we track are Light and 13 are Tank.
How many pets compete for the same slot
15 of the other 53 pets also buff Light and Tank, so this is a contested niche — you have alternatives if you do not own this one.
CRIT RES effect
7 of the 54 pets we track lead with a CRIT RES effect.
Both effects, two different rules
The Companion effect (Light Ally Max HP +9%) applies only while this pet is one of your three equipped companions. The Ownership effect (Tank Cookie CRIT RES 0.14%) applies from the moment you own it, equipped or not — which is why pulling a pet you never equip is still worth something.
